Can you tell me where...

    Can you tell me where I can buy or get info on the solar cells that power calculators.  I need them in quantities of >100.  Everywhere I look on the internet they sell big ones but what I need for a product is a way to get 3.3 V to 5 V at 1->5ma in a package that consumes less than 3X4 and works with incandesant and low light levels.
