solar cells

[coramdeo831]

Hi, sorry if this is a wrong place for my question, but I was wondering if I could get any help about building solar cells.

 

My task is to build a solar cell with different thickness of antirelective coating..

 

1. Does anyone know when is the appropriate time to cover the solar cell with the coating while building it?

 

 

2. When solar cells are made from cuprous oxide instead of silicon, does the antirelective coating have any effect on the amount of light the solar cell absorbs?

 

 

I'm sorry if these questions are too general, but any comments would help.

I don't think that AR coatings will usually survive further processing. They tend to have a fairly low temperature threshold for damage - I've ruined coatings with a routine vacuum system bakeout. Generally they are added last to optics, but of course it depends on the specific coating you use.
