There is some controversy brewing in the solar cell production environments and it has nothing to do with anyone on Dancing with the Stars. Sorry, that’s my attempt at levity…yes, I won’t quit my day job.
Flexible solar cells with an 18.7% record efficiency developed by scientists at Empa, the Swiss Federal Laboratories for Materials Science and Technology were recently reported on Science Daily. That is approaching the CIGS on glass substrates with processes where CIGS layers are grown at temperatures of 600 °C or above.
This can be a game changer in solar cell development and costs to produce. So far the flexible solar cells on polymer films have been far behind in performance compared to rigid cells. This is primarily because polymer films require lower temperatures during deposition of the absorber layer, generally resulting in lower efficiencies. The breakthrough is if cost to product is lower and efficiencies are similar it can change an entire industry.
