Researchers from the Centre for Solar Energy and Hydrogen Study Baden-Württemberg (ZSW) have actually accomplished 21.1 percent efficiency with tandem perovskite - CIGS solar cells. These thin-film-based modules are very efficient, light and flexible as well as can open doors to lots of new usage cases for which standard rigid modules are not suitable.

Researchers in Germany aimed to get rid of making use of harmful solvents in the manufacturing of perovskite solar cells, changing them with a much more environmentally worldly called dimethyl sulfoxide (DMSO) which has so far shown difficult to integrate right into processes appropriate for large-scale production.
