Ask HN: What weird or hard problems are you trying to solve?
I&#x27;m working on an fully open source Physical Vapor Deposition System which is capable of producing thin flim solar cells, Ex(CIGS,CDTE) at efficiencies in the range of 15- 20%.  The system is designed to produce one 10 watt cell for every 45 minutes. I could go into further depth here but for obvious reasons It would take me a while to explain everything.
