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

ABSTRACT: Perovskite and organic semiconductors exhibit analogous properties, including bandgap tunability, low-temperature solution processing, and high potential for lightweight applications. These similarities render them highly attractive for being integrated in multijunction architecture: perovskite-organic tandem solar cells (POTSCs). Nevertheless, the efficiency of POTSCs is limited by electrical losses, which stem from both the wide-bandgap (WBG) perovskite layers and the interconnecting layers (ICLs) between two subcells. These two essential components also constrain the tandem device stability. In this study, the underlying cause of open-circuit voltage (V_OC) losses in WBG perovskites is identified, which is ascribed to the presence of mobile defects distributed at surface regio
