and that’s where this book will come in handy: http://www.porous-35.com/index.html
Here’s a firm using a technology called “Ovonics”, one application of which is thin-film PV. http://www.uni-solar.com/uni-solar-difference/technology/ . It uses 3 tuned layers on flexible steel substrate, total <1.0 mm.

Stanford Ovshinsky, president, chief scientist and technologist at Energy Conversion Devices, Inc. (ECD Ovonics; http://www.ovonic.com; Rochester Hills, MI), says his firm has developed a nanocontrol device that has the potential to replace transistors. The all thin-film device is said to have significant multifunctional capabilities when compared to transistors, thanks to its high current carrying capacity and unique modulation gain.
The bio of the inventor is here: http://en.wikipedia.org/wiki/Stanford_R._Ovshinsky
He’s gone independent, again, to explore wider applications. “Ovshinsky Innovatons, LLC”. Might be worth giving a call (Troy, MI). (248) 408-3847
