Unraveling the defect landscape of wide-bandgap perovskites from electrical and photoelectrical characterization of thin films and solar cells
By integrating electrical and photoelectrical characterization techniques with advanced numerical simulations, this study deciphers the defect landscape of wide-bandgap perovskite thin films, distinguishing between mobile ionic defects and recombination-active electronic states to reveal their specific energy distributions, concentrations, and mobilities.
