How Do Surface Polar Molecules Contribute to High Open‐Circuit Voltage in Perovskite Solar Cells?

Abstract To date, the improvement of open‐circuit voltage (VOC) offers a breakthrough for the performance of perovskite solar cells (PSCs) toward their theoretical limit. Surface modification through organic ammonium halide salts (e.g., phenethylammonium ions PEA+ and phenmethylammonium ions PMA+) i...
