Defect Dynamics and Solution‐Processed Interconnects in Perovskite‐Organic Tandem Solar Cells

Advanced Science, EarlyView.
In this study, we identify the underlying cause of efficiency losses in WBG perovskites, which is ascribed to the presence of mobile defects distributed at surface regions. We further employ effective passivation agent with functional chemical groups to facilitate the healing of the mobile defects, thereby enhancing the VOC to 1.35 V and champion ...
