Despite the numerous efforts to optimize the performance of perovskite solarcells (PSCs), challenges persist. Carbon materials are promising candidatesfor this purpose, but identifying the most suitable carbon material andunderstanding its role in the PSC among the wide family of carbons remains achallenging task. In this study, SCAPS-1D software is employed to optimizethe use of carbon materials as interlayers to PSCs. The best configuration ofthe carbon interlayer and the required physicochemical properties of thecarbon materials is identified for improved performance. The simulationsshow that the insertion of thin carbon interlayers of adequate features in n-i-pstacked cells (FTO/TiO2 /MAPbI 3 /HTL/Ni) can increase the efficiency of theresulting PSCs by over 2.3 %, while significantly improving the open-circuitvoltage and the fill factor. These results underline that those carbon materialswith optical bandgaps ranging from 3 to 3.5 eV offer the best performance asan interlayer to the hole tranport layer, with negligible impact of the thicknessof the interlayer. This contribution offers a novel perspective on the use ofcarbon materials in PSCs and provides new insights into the understanding ofthe role of carbon materials as interlayers in PSCs |
