I have flipped normal of object, but unlucky, it didn't work in render. Is there way to fix it?

Two years late, but for reference :)
If you want to have backface culling in cycles you can use a material setup like this:
Which basically uses two materials, a diffuse one (or whichever one you want) and a transparent material (to cull backfacing surfaces). You just mix them using the backfacing output of the geometry node so that backfacing surfaces use the transparent material.
