A simulation study around investigating the effect of polymers on the structure and performance of a perovskite solar cell
Polymers are a very vast classification of materials that possess a lot of applications in various industries. For instance, they have application in structure modification of the perovskite solar cells (PSCs). Polymers’ application in perovskite solar cells can be divided into their usage as hole-transporting materials (HTMs) and the ultrathin interfaces between hole transporting materials and the perovskite layer. In the present research, we tried to highlight this application from the simulation perspective using SCAPS-1D software. For this purpose, this study investigates the effect of using different polymeric HTMs and interfaces from the photovoltaic parameters view. The total PSC structure was in the form of Au (Back contact)/ HTM/ polymeric Interface (if there are)/ CH3NH3PbI3 (absorber)/ TiO2 (Electron Transporting Material: ETM)/FTO (counter electrode). Results represented the best hole transporting material and interface as PEDOT:PSS and P3HT layers. The final efficiency was obtained at 18.77% with the optimal mentioned layers’ materials.
