Özet

A detailed fabrication method is represented for perovskite solar cells, incorporating various materials and processes based on glove box-free sol-gel deposition routes. Key components include NiOx HTL, PC61BM ETL, BCP HBL, and CH3NH3PbI3 perovskite absorber. Results reveal a significant influence of PC61BM concentration on device efficiency, with champion cells exhibiting optimized VOC, JSC, and FF values at a specific concentration. Statistical analysis of 38 devices confirms the reproducibility and consistency of this concentration, yielding a PCE of 18.2 %. This study investigates a gap in the literature by clarifying the impact of PC61BM solution concentration as a sol-gel deposited electron transport layer. By identifying the optimal concentration and its role in improving device efficiency and reproducibility, investigation contributes to advancing the field of fully sol-gel-based perovskite solar cell technology.
