Photovoltaics and Climate Change
At the COP21 event held in Paris in 2015, the world debated how to deal with
the challenge of climate change due to the CO2 increase in the atmosphere. The
COP21 debates resulted in a milestone that almost all governments worldwide
agreed upon: to limit the temperature increase to 1.5 °C. This in turn means that
the transition of the energy system from fossil to renewable energy
sources must be accelerated. Almost all energy system scenarios show that
photovoltaic (PV) technology will be the main pillar of the future energy supply.
Market and Photovoltaic Production
Due to this fact the PV market will grow rapidly; up to 12 TW1
are expected to
be installed in 2030 worldwide2
. This is an impressive increase compared with
today’s installed capacity of about 630 GW. Many countries have just started to
install PV on a larger scale. Thus, the PV market is a great opportunity for
the manufacturing industry. Europe was leading the manufacturing of PV at
the beginning of the 21st
century and is still leading today in the field of R&D.
However, since 2007 China has been much more successful in setting-up PV
production capacity since the Chinese government recognized the strategic and
political impact which the leadership in a technology with such a gigantic market
growth would bring. Chinese companies received strong support while Europe
lost its leadership position in PV production. A chance still exists, however, for
Europe to play a role in this big future market. Now is the right time to invest
in PV manufacturing in Europe, especially since more PV must inevitably be
installed in order to fulfill the climate goals agreed upon in Paris. Further cost
reduction, new business models and progress in system and battery technologies
will lead to more PV installations in Europe. Hence, the European home mar-
ket must and will grow substantially beyond several tens of GW per year
as many analyses confirm3

PV Production and Sustainability – New High-Tech
Solutions
Europe should use this chance to cover a large share of its domestic energy mar-
ket with European products. This is not only a big opportunity for high-tech
manufacturing in Europe, but also a chance to ensure energy security by
reducing dependency on imports in the sensitive field of energy genera-
tion. Another crucial factor is sustainability. Why transport large and heavy PV
modules the long distance from Asia and cause CO2 emissions and adding cost?
For example, module costs of 20 €cents/W can be soon realized, and transport
costs from China to Europe can be up to 2.5 €cents/W. Moreover, during the
production sequence of the PV modules, CO2 and other environmentally harmful
emissions occur. These emissions need to be minimized and in Europe strict con-
trols are already now imposed for this purpose. Thinking about cycling economy,
cradle-to-cradle, and recycling concepts, Europe is predestined to introduce real
sustainability into the energy system and provide real »green« energy1
. Further-
more, the global demand for solar products is going to reach massive volume
with the emergence of markets in all countries of the world. By taking a leading
role in providing the world with sustainable PV products, Europe would secure its
economic future and will be the source for premium products2
.
This vision of high-tech and sustainable PV production along the value
chain in Europe can become reality since R&D centers in Europe already provide
efficient and more sustainable technologies compared to today’s world mar-
ket products. For example, there is progress for manufacturing poly-Silicon and
wafers more sustainable using less energy. Kerfless wafer technologies are under
development in the R&D centers. Higher efficiencies for solar cells – which reduce
the area required – for different cell technologies are available and ready to be
transferred into industrial production. Moreover, tandem solar cell structures are
progressing fastly and achieved already higher efficiencies than single-junction
solar cells. For PV modules, technologies reducing the cell-to-module losses are
ready for production. All these technologies are more sustainable than today’s
PV products and require fewer resources, but are at the same time cost competi-
tive on a system level.

Annex
In the following details and background information are presented to underline
the idea of a 10 GW GreenFab.
Realization
In order to compete in the world market, it is important that Champions can
emerge. This includes, among other things, a sufficient size. Therefore, a produc-
tion size of 10 GW is proposed, which is then continuously expanded. The crea-
tion of photovoltaic production along the value chain from wafer to module
would create up to 7,500 new jobs and continue to provide many jobs in the
supply industry that could be lost in the medium term if no PV manufacturing is
set up in Europe. These jobs are long-term. In addition, the installation of PV
systems creates additional jobs. The installation of 1 GW per year corresponds to
about 3,500 full-time jobs.
Thus, the high-tech production of PV modules along the value chain
brings benefits for Europe as a whole - and for regions where industrial
production is located in particular.
Sites where structural changes are pending for political reasons or which are to
be developed in terms of industrial policy are particularly suitable as a nucleus for
a 10 GW PV production. Locations are conceivable where local characteristics are
given, e.g. in the coal regions in North Rhine-Westphalia or Lausitz or in Croatia,
where there is a national interest in promoting industrial sites.
The Multi-Regional Approach
The 10 GW GreenFab can be also realized by combining different sites with at
least 1 GW manufacturing capacity each. This would allow to receiving regional
local support. Each single manufacturing site can be a copy of the others. In any
case it is important that the purchase, sales and administration is in one hand.
This multi-regional approach allows also including already existing sites into the
10 GW GreenFab concept. For the realization of this approach the EU has to
consider the PV sector as Strategic Value Chain and go towards IPCEI.

Frequently Asked Questions
The European solar cell and module manufacturers have all disappeared
from the market. The production for mass products takes place in the
Asian region. Can Europe really compete with cheap production?
PV production technology has been undergoing rapid innovation cycles. This is
the reason why strong cost and price reductions in the photovoltaic sector have
become possible. Since 2007, when Europe was still the market leader in PV
production, efficiency has increased by 40 %, productivity by 400 % and global
production capacity by 40 times. This is a merit of the PV producers, based to a
large extent on the innovations in mechanical engineering and material manufac-
turing, a process which constantly needed new investments. The required finan-
cial flows for investments were provided in China. European companies could
not keep up and have therefore disappeared from the market. It should be noted
that also in China many companies have disappeared from the market and the
PV market leader changes almost every year.
Technologically, Europe is still leading, and also mass production is possible in
Europe, as the automotive industry demonstrates. Thus, there is no reason why
mass production should not take place in Europe at world market prices1
.
Existing »old« companies in Europe (as the SolarWorld example shows) were
unable to streamline their internal structures and respond dynamically and agile
to the rapidly changing market. With a restart of PV production in Europe, there
is no »inherited burden«.
Why should European companies now succeed in the market?
Today's production of PV products is fully automated – also in China and other
Asian countries. The personnel costs are thus negligible during production. Yield
and quality assurance are at the highest level in Europe. Therefore, PV can be
produced at the same low cost as in the Asian region. A decisive prerequisite for
success is full integration from the wafer to the module (ideally up to the energy
supplier as operator of PV power plants). This means independence from pur-
chasing components as wafers and cells. It is also a prerequisite that the pur-
chase for large quantities (10 GW) takes place centrally.
In addition, the modules are currently being produced at costs of 25 €cents/W.
With further innovations 20 €cent/W will be possible. As a result, the overall cost
distribution shifts – especially in the direction of logistics. Therefore, local and
fully integrated production is an advantage. At the same time, local production
enables strategic autonomy in the energy sector, as requested, for example, by
Maroš Šefčovič as a member of the European Commission.
Why sustainability? Does this make the module more expensive?
Sustainability includes energy and resource efficient production technology which
aims for higher efficiencies and lower material consumption, a longer lifetime for
modules and the most complete reuse of materials at the end of their lifetime. If this
is taken into account from the beginning in the planning of a production as well as
in the cell and module design, the PV module will not be more expensive. Ultimate-
ly, the reduced use of materials and energy will make it possible to cut costs overall.

What has changed since previous initiatives, such as the x-GW ini-
tiative in 2013/14?
Ultimately, the x-GW concept is still right. However, with a meanwhile grown
market it turns out that x should rather be 10, meaning that a size of 10 GW
should be implemented as a first step. This size makes sense for global competi-
tiveness today.
What has also changed is that the CAPEX costs have fallen significantly in recent
years and that the Al-BSF cell structure has been replaced by the highly efficient
PERC structure in industrial production. Further cell architectures with even high-
er efficiency potential have been developed in European laboratories and are
thus available for industrial implementation.
The already significant cost reduction and the prospect of even further reducing
the cost in PV production leads to the conclusion that local production can bring
cost advantages. This is a new development.
Furthermore, the reduction of CO2 emissions is even more strongly on the agen-
da of all countries. This can only be done with wind and PV technology. To meet
this goal, the PV market – including in Europe – will have to grow substantially.
That is why now the right time to invest is. The local market will be available for
the take-off of the products.
Is it possible to find investors for a 10 GW GreenFab?
The initiative is intended to awaken politics, society and the economy, and to
point out the commercial opportunities for investors. No investment is without
risk. However, the boundary conditions have changed a lot in recent years. The
initiators are ready to work out concrete business plans with investors.
The initiative has a strong political and strategic aspect because the independ-
ence and security of energy supply is a central concern of society. It is necessary
to create framework conditions that provide sufficient security for investors.
The European market will grow substantially with or without the 10 GW Green-
Fab. The question though is, if modules are being produced 100% outside of
Europe or if at least part of the market will be served by local European produc-
tion. Also for an Asian PV manufacturer an investment in European production
could be strategically important to avoid transport cost and cost possibly arising
for products with higher CO2 footprints.
PV technology has already proven today that it is the cheapest and most sustain-
able source of energy in every respect. If it is possible to work out a coordinat-
ed implementation concept via the European Commission through coop-
eration between countries (such as France-Germany, Germany-Poland, Croa-
tia-Germany ...) and other regions, and considering the today´s overall political
situation, the chances high to find investors.

Background Data and Facts
In the following, some relevant facts are shown which underline the potential of
a 10 GW GreenFab.
Market
The Sky scenario created by Shell illustrates how the primary energy deployment
could develop worldwide by 2100. Ultimately, PV technology will be central to
the global energy supply. It will thus create a very large market. Today we are
only at the beginning of development. (see: https://www.shell.com/energy-and-
innovation/the-energy-future/scenarios/shell-scenario-sky.html)
Many scenarios, for example from Solar Power Europe also expect a strong
growth of the European PV Market already in the short term. The main drivers
being the binding national targets for renewable in many EU-28 countries lead-
ing to high tender volumes, the strong price decrease due to the restructuring of
the Chinese market as well as activities of utilities, corporates, and big funds in
Europe who invest in PV as both the lowest cost and most versatile energy gen-
eration source.
European annual solar PV market and scenario until 2023 (Source: Solar Power
Europe). The expected growth of the European market is also underlined by the
national targets. Some of those are listed in the following.

German market
Currently, installations of up to 2.5 GW/year are planned. This installation capaci-
ty is not sufficient to meet the CO2 targets. Therefore, this cap is currently in the
political discussions. As agreed within the framework of the formation of the
government, an additional 4 GW photovoltaic will be realized in special tenders
from 2019 to 2021. Actually a limit for up to 2.5 GW per year is
seen. https://www.solarserver.de/solar-

Spanish market
Strong cuts in PV production led to a sharp decline in PV installations in Spain in
the late 2000s. Now a turnaround is emerging: The Spanish government aims to
provide 35 % renewable energy by 2030, which will require around 50 to 60
GW of photovoltaic power. Currently there are about 8.7 GW installed in Spain,
of which 4 GW were added in 2019.

Prices for PV Produced Electricity

Future of Solar Photovoltaics, Report, IRENA, 2019
The graph shows Levelized Costs of Electricity (LCOE) in US$/kWh for projects and
global weighted average values for solar photovoltaica. PV electricity has seen a
very significant price reduction. Prices below coal and nuclear power generation
are possible. This makes PV power competitive! In the last years tenders for energy
installations were implemented where PV power was by far the cheapest form of
energy. Due to the low electricity production costs of PV, the market for PV will
grow and new markets will open up.
Job Creation
Correlation between PV domestic market and job creation: A growing PV market
in Europe will foster a high number of jobs in Europe. (Data 1990-2016: Jobs

Aspects of Sustainability
The European 2030 climate and energy framework sets key targets for the year
2030 (Source: European commission, COM (2014) 15 final/2). Without PV tech-
nology the goals can be hardly achieved.
Life cycle analyzes carried out for PV installations highlight the potential for more
sustainable PV production and installation. The graph clearly shows that the
greatest potential for all Product Environmental Footprint Category (PEFCs) lies in
material flow and production towards the module (see also: http://www.etip-

Solar panel manufacturers need electricity and thermal energy. Carbon emissions
can vary widely with location. For example, panels produced in China, which
relies heavily on coal for power, have a larger carbon footprint than those pro-
duced in Europe. The effect of a CO2-prize on the carbon footprint of PV mod-
ules is also shown. Such a system is currently being discussed in Europe.

Recycling
Today’s view on the value chain in PV:
Only the cost up to the module is considered. Costs for recycling are not yet
regraded.
Future, sustainable view:
At the end of the life cycle nearly 100 % of the parts of a module will be made
available for a new life cycle. The cost for the recycling process must be consid-
ered at the beginning of the cycles.
