Monolithic perovskite/organic tandem solar cells with 23.6% efficiency enabled by reduced voltage losses and optimized interconnecting layer

Wei Chen et al.

Summary: Perovskite/organic tandem solar cells have a promising future in thin-film photovoltaics due to the large chemical composition and tunability of their bandgap.
