I had to create some solar cells and was looking for textures. Unfortunately I didn’t find anything usable; especially I was missing a raw texture of the bluish cells themselves with good variations and as a tillable texture.
I started thinking of how it could be achieved. Reference patterns appeared to consist of sharp and random shapes and I thought a distortion effect would help me.
After messing around with Photoshop I came up with this:
This might not be a real solar cell pattern but it is close enough for me, especially I can edit and tweak it as I want.
This tutorial is not aimed for pure beginners. You should have some knowledge of image editing. Photoshop was used but it should be achievable with similar techniques with other tools
