Reply #10: I read it not as a gloat, but as ignorance

The Sharp thin-film PV technology is amorphous Si, not III-V's.

Your irrelevant snippet including "Lumiwall products also incorporate electroluminescent materials including gallium and arsenic" demonstrates your ignorance that the most common III-V material is gallium arsenide.

a-Si cells are made by chemical vapor deposition using silane as a feed material.

That said, any semiconductor-based PV technology is likely to produce the wonderful results on groundwater that has been associated with EVERY large semiconductor facility.
