Flexible solar cells with record efficiency of 22.2%

One year after announcing an efficiency record, Empa scientists have achieved a new mark of 22.2% for flexible CIGS solar cell on polymer film. Solar cells of this type are especially suited for applications on buildings, vehicles, satellites, airships, and mobile devices. Empa researchers have – once again – improved the efficiency of CIGS flexible Read more about Flexible solar cells with record efficiency of 22.2%[…]

Efficiency of flexible solar cells to a new limit

A group of scientists at Empa has pushed the efficiency of flexible solar cells to a new limit. Independent measurements revealed an efficiency of 21.4 percent when these types of solar cells convert light into electricity. For comparison: the best efficiency of a non-flexible solar cell made of crystalline silicon is reported at 26.7 percent. Read more about Efficiency of flexible solar cells to a new limit[…]
