3D Mapping Reveals Defect Suppression in SG-Passivated Perovskite Devices.

Caption

A comparative 3D visualization of trap state distributions in perovskite solar cells, showing both energy (left) and spatial (right) profiles. The sulfa guanidine (SG)-treated “Target” device exhibits significantly reduced trap densities compared to the untreated “Control,” highlighting the effectiveness of internal bulk passivation in improving device performance.
