Lead-free perovskite solar cell with potential efficiency of 27.4%
Scientists in India have simulated a perovskite cell based on methylammonium tin iodide which they claim may achieve a short circuit current density of 25.97 mA per square centimeter, an open-circuit voltage of 1.203 V, and a fill factor of 87.79%. The cell is composed of a fluorine-doped tin oxide (FTO) substrate, a titanium oxide layer, a methylammonium tin iodide perovskite film, a copper oxide hole transport layer (HTL), and a layer made of gold (Au).
