SEOUL A team of researchers based in South Korea and Switzerland set a new record of 25.6 percent in the power conversion efficiency of perovskite solar cells by introducing an anion engineering concept that uses pseudo-halide anion formate to suppress anion-vacancy defects and augment crystallinity.
A perovskite solar cell includes a perovskite structured compound as the light-harvesting active layer. The high absorption coefficient of perovskite solar cells enables ultrathin films to absorb the complete visible solar spectrum, leading to the creation of low-cost, efficient, thin and flexible solar modules.
