A new efficiency record of 21.4% for flexible CIGS solar cell on polymer film has been achieved by scientists at Empa. Solar cells of this type are especially suited for applications on roofs, transport vehicles or mobile devices. 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...
