What types solar cells are better for use in solar panels?

DIY Solar Power Question

I am really good with my hands, I rebuild cars and I rewired my house. The next project I want to do myself is build my own solar panels and use them to power at least some of my electrical needs.

I have done a fair amount of research on solar power kits and residential solar power in general But I have one question that is still bugging me and I hope someone can help.

• Amorphous cells
• Polycrystalline cells
• Single-Cell Solar cells

Can you tell me which one is better according to power produced? Also do any of them have side effects or problems that I need to be aware of?
