Perovskite solar cells (PSCs) have made tremendous strides in device performance and power conversion efficiency (PCE), which has given the photovoltaic field as a whole a sense of accomplishment recently. The conventional structure of perovskite solar cells (PSCs) consists of many layers that are necessary for their operation. A perovskite layer for absorption and other layers for charge extraction and transport are the fundamental parts of a perovskite solar cell. The negative and positive charges are transported by these extra layers, which could be an electron-transport layer (ETL) or a hole-transport layer (HTL), respectively. Nonetheless, there are certain drawbacks on the current conventional structure of hole-transport material (HTM) used which has greater cost and requires equivalent dopants which eventually turned out to be Perovskite Solar Cells instability caused by the humidity. Therefore, implementing Graphene Oxide (GO) as a Hole Transport Material that offers both inexpensive and has a good Hole Transport Layer interface plays an essential role to attain high Perovskite Solar Cells performance. The design on introducing thin layer of graphene oxide (GO) on hole transport material (HTM) for perovskite solar cell is further analyzed. Regarding this, the aim of the research is to simulate the thin layer Graphene Oxide as Hole Transport Material (HTM) in perovskite solar cell using SCAPs simulator and to analyse the performance of thin layer Graphene Oxide (GO) as Hole Transport Material (HTM) for perovskite solar cell.
