In Situ Impurity Phase Repair Strategy Enables Highly-Efficient Perovskite Solar Cells with Periodic Photovoltaic Performance
{{output}}
The photoactive α-phase of formamidinium lead iodide perovskite (α-FAPbI3) is regarded as one of the ideal materials for high-efficiency perovskite solar cells (PSCs) due to its superior optoelectronic properties. However, during the deposition of α-FAPbI3 ... ...
