Suppressing ZnO-Induced Decomposition in Perovskite Solar Cells via Glycine-Based Chelation Strategy.

ABSTRACT: Organic-inorganic perovskite solar cells (PSCs) are a promising technology in renewable energy due to their high efficiency and low cost. The electron transport layer (ETL) plays a very important role in improving device performance by minimizing recombination losses and selective electron contact. In solar cells, zinc oxide (ZnO) is the most favored ETL due to its visible transparency, suitable energy level, excellent electron mobility, and structural flexibility. Nevertheless, the current application of ZnO in PSCs is restricted by the undesirable reverse decomposition reaction at the ZnO/perovskite (PVK) interface. The presence of surface hydroxyl (-OH) groups and interstitial zinc ions (Zn²⁺) speeds up the decomposition process. This process deteriorates the charge-collectin
