Abstract :
Herein, a famous amino acid, cysteine (LC), apply as an available and low cost additive to construct perovskite solar cells based on Sn (Sn-PSCs). A carbon cell configuration is used to decrease the costs. In this study, we try to solve one of the most important issues in Sn-PSCs, the tin oxidation phenomenon. Because, oxidation phenomenon results in p-type doping and severe device deterioration and low performance in Sn-PSCs. Our results reveal that the adding of LC improves the photovoltaic parameters as a result of an effective decrease in Sn+2 oxidation. LC is a proper alternative for expensive additives to decrease tin oxidation. It is found that this strategy will open up a promising direction to application of these kinds of additives in the fabrication of Sn-PSCs.
