Uncle_bob you could re-purpose the solar cell from the FO Solar Pod if you didn't want to use it any more..... it only has two short wires on it that goes to teh PCB, quick snip and you're done

I bought some of those cheap solar cell elements on ebay, and I can package a few up and post to Canberra if you like. A couple of smaller pieces will let you "tune" the size to your requirements too
