Design and construction of single cation perovskite solar cell and its stability in a solar cell system and their efficiency

During the last few years, the construction of new generation perovskite solar cells based on perovskite absorbent materials has grown greatly compared to other photovoltaic cells. The reason for this is the rapid growth of cell efficiency, easy manufacturing method and low cost. Of course, in addition to these advantages, there are limitations such as low stability and high sensitivity to humidity, as well as their productivity during the usable period, which has provided attractive fields for work. In this article, a ۳CH۳NH۳PbI single-cation perovskite solar cell with dimensions of ۱.۴cm*۱.۴cm and an active area of ۹.۹۰cm۲ has been made and its performance has been carefully analyzed in different time intervals. The results show that the maximum open circuit voltage obtained is about ۹.۰۹V, the maximum short circuit current density is ۱۱.۲mA/cm, the highest efficiency is ۰.۹۰% and the maximum filling factor is ۹.۱۱. The voltage of these cells has been analyzed immediately after the gold electrode coating and also ۴۴ and ۴۴ hours after that.(۱,۲)
