My experience on Perovskites solar cells (PSCs) comes from IER-UNAM, where I had the opportunity to take a 1-week course with Dra. Hailin research group. Here, we developed some MAPbI3 Perovskite solar cells with regular n-i-p architecture. Due to the fabrication protocol they were following, we could develop PSCs of up to 12% in our first attempt. Workshop - Development of Hybrid Perovskite Solar Cells - IER-UNAM, June 2019. Imagine how it feels to fabricate a device of 12% of conversión energy in your first week of experimental research. That is the magic of perovskite materials because it is easy…
