Physical understanding of defects in perovskites for a science-based approach to improve the stability of perovskite solar cells KU Leuven
Perovskite solar cells (PSCs) were introduced in 2009, only achieving 3.8% power conversion efficiency (PCE). A rapid increase in effiency has followed ever since, achieving already 23% PCE nowadays. In this perspective, it can already start to compete with crystalline silicon (c-Si) solar cells, which represent more than 90% of the market. Also, the abundancy of the materials and their low cost, combined with the low-temperature, simple ...
