Researchers identify main source of wide-bandgap solar perovskite degradation

Scientists in Belgium have investigated how perovskite absorbers used in solar cell degrade under three different stress test types and have found that the interface between the perovskite layer and the electron transport layer suffers from weak thermomechanical stability, which creates the conditions for performance losses.Researchers from imec, Hasselt University, and Ghent University in Belgium have investigated the impact of light and heat on the degradation of wide-bandgap perovskite solar cells and have found that the devices' charge transport layers are the main source of performance losses. ...
