Tandem Solar Cells
Light‐induced phase segregation is the chief culprit for the open‐circuit voltage deficit and photo‐instability in mix‐halide perovskite solar cells with wide‐bandgap. In article number 2203319, Xuegong Yu and co‐workers report a highly efficient and photo‐stable wide‐bandgap perovskite solar cell with a top‐ranking open‐circuit voltage of 1.24 V realized by defects management in...
Wide‐bandgap perovskite solar cells (PSCs) with an optimal bandgap between 1.7 and 1.8 eV are critical to realize highly efficient and cost‐competitive silicon tandem solar cells (TSCs). However, such wide‐bandgap PSCs easily suffer from phase segregation, leading to performance degradation under operation. Here, it is evident that ammonium diethyldithiocarbamate (ADDC) can reduce the detrimental...
