Perovskite solar cells in p–i–n architecture passivated with a PEAI-based 2D perovskite show a strong short-circuit current loss with a simultaneous increase in V OCbut a rather constant FF.
Moreover, the charge collection losses at short-circuit conditions in Sn-based perovskites can be caused by an insufficient charge carrier diffusion length due to electronic defects, which would also negatively affect the open-circuit voltage.
Accordingly, it has also been shown that perovskite devices exhibit substantial PL emission even at short-circuit conditions, meaning that charge extraction is not yet fully optimized and a significant fraction of charges still undergo recombination within the bulk of the perovskite absorber layer, even at short-circuit 14.
In addition to the mentioned losses induced by bulk or interface modifications, a recent study identifies ionic space charges as the origin of transient current loss in perovskite solar cells.
The released electrons then move through an electron transport layer (ETL), facilitating their transport towards the battery. At the interface between the perovskite solar cell and the LIB, an electrolyte or electrolyte medium is present, allowing the migration of lithium ions.
Series resistance (Rs) within a perovskite solar cell has a substantial effect on its electrical characteristics and overall performance of the solar cell device structure.
