Chinese researchers build 21.60%-efficient perovskite solar modules via blade coating

A research team led by the Dalian Institute of Chemical Physics in China have used tetramethylammonium chloride in the fabrication of perovskite solar cells and modules, demonstrating that it improved both stability and efficiency results. The group's 10 cm × 8 cm modules achieved certified 21. 60% power conversion efficiency. The novel interfacial modification enabled the use of scalable blade coating to deposit both transport layers and the perovskite layer. Researchers led by the Dalian Institute of Chemical Physics (DICP) have used tetramethylammonium chloride in a tin(IV) oxide electron ...
