Another alternative to silicon cells that is actively being researched is perovskites:
> Perovskite solar cells hold an advantage over traditional silicon solar cells in the simplicity of their processing and their tolerance to internal defects. Traditional silicon cells require expensive, multi-step processes, conducted at high temperatures (>1000 °C) under high vacuum in special cleanroom facilities. Meanwhile, the hybrid organic-inorganic perovskite material can be manufactured with simpler wet chemistry techniques in a traditional lab environment.

- pflanze 4y agoThe mentioned advantage seems dubious considering that the only cell type for which that is currently true is those using lead, for which the toxicity issue isn't solved. Trading the complexity of the cleanroom facility for the complexity of lead containment doesn't appear to be a good choice. The tin based cells might look interesting though. PS. OTOH I wasn't aware that Si based panels might have lead in them, too (even though much less?) as per https://news.ycombinator.com/item?id=32283432 https://news.ycombinator.com/item?id=32283432
