CIGS-perovskite tandem cell New!

15 May 2019

Scientists at Solliance, in collaboration with MiaSolé Hi-Tech Corp., fabricated a flexible solar cell with a power conversion efficiency of 21.5%. The solar cell combines two thin-film solar cell technologies into a 4 terminal tandem solar cell stack: a top flexible semi-transparent perovskite solar cell with a bottom flexible copper indium gallium selenide (CIGS) cell. CIGS technology has been successfully used to produce high efficiency flexible and lightweight cells and modules, which address markets where heavy and rigid panels cannot be used. Perovskite solar cells, despite being a relatively young technology, have already achieved high efficiencies, and promise low cost solar technology based on abundant materials. Combining both technologies in a flexible and lightweight package expands the horizon of high performance, flexible, and customizable solar technology.
