Abstract

The efficiency of Sn-perovskite solar (Sn-PVK) cells was enhanced by adding 1% Samarium iodide (SmI₂). Increase in J_sc and FF is associated with the enhancement of efficiency and and explained by lower series resistance. SmI₂ is known as a strong reducing agent and is oxidized to Sm³⁺ by reducing a substrate. By adding 1 and 5% SmI₂, the carrier concentration of Sn-perovskite layer due to the presence of Sn⁴⁺ was decreased from 4.8
