n situ GIWAXS characterization using synchrotron radiation helps overcome challenges in wide-bandgap perovskites
Wide bandgap perovskites are key light-absorbing materials for preparing high-efficiency perovskite/organic tandem solar cells. To achieve spectral matching with the narrow bandgap organic rear cell, a higher proportion of bromine is usually introduced into the perovskite composition. However, due to the different crystallization rates of iodine and bromine components during film formation, the ph...
