Reduction of fabrication time for organic-inorganic hybrid perovskite solar cells in lab-scale

초록

Although perovskite solar cells (PSCs) have attracted significant attention due to their outstanding performance, the optimization of PSC fabrication remains challenging, requiring tremendous amounts of experiments because of the diversity in perovskite compositions and the different concentrations of charge transport layers. Herein, we introduced methodologies to effectively reduce the fabrication time of PSCs. We focused on each step: substrate washing, electron transport layer coating, and perovskite layer coating. Through these steps, we could successfully reduce the overall fabrication time to 49.2% of its previous duration. Furthermore, this method significantly reduces the defect rate from 18.6% to 6.3%, thereby improving the reproducibility and performance of PSCs simultaneously.
