Use of a perovskite layer to boost the efficiency of CIGS modules

摘要

Perovskite microcrystals have properties that make them uniquely suitable as a basis of thin, light, semitransparent solar modules. However, there are some remaining challenges, including lifelong stability, that need to be tackled before this technology can become commercially available. Once these have been resolved, perovskites can also be deployed for boosting established solar technology, such as silicon or copper indium gallium selenide (CIGS) modules. As an example, a record efficiency of 17.8% has recently been reported for a stacked perovskite/CIGS module, surpassing the highest efficiencies achieved so far for both stand-alone perovskite modules and CIGS modules.
