DIY Solar Cells through screen printing
I was wondering if anyone has seen the "plans" offered by fuellessamerica.com on producing solar cells cheaply and at home through screen printing. They claim efficiencies of 12-14% can be achieved. I know most solar cells are screen printed, but I know the doping can be difficult. Has anyone seen/done this? I have seen the American patent held by a Japanese company that outlines the process. I didn't have much time to peruse it however. I did notice they were using correct terminology, but it was obviously geared towards commercial enterprise. Any thoughts?
