The principles of p-n junction used to describe silicon based solar cells are still applicable to characterize the properties of perovskite solar cells. A number of authors treated perovskite solar cells as p-n, p-i-n and n-i-p junctions solar cell.
Photo-charged battery devices are an attractive technology but suffer from low photo-electric storage conversion efficiency and poor cycling stability. Here, the authors demonstrate the use of perovskite solar cells in conjunction with a lithium ion battery which displays excellent properties.
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.
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.
In perovskite solar cells, adjusting the voltage can significantly impact the device's capacitance, which is also a measure of its charge storage capacity. For PSCs, capacitance relates closely to the materials' electronic properties.
