Tin perovskite solar cells are environmentally friendly, however improvement of stability is necessary because Sn is easy to be oxidized. In this study, we focused on APF, a fullerene derivative containing a pyrrolidine ring as an antioxidant compound. Antioxidant properties of APF were confirmed and the solubility of APF becomes better compared with fullerenes. APF was incorporated into the perovskite layer, and XRD and XPS measurements were performed to evaluate the stability of the perovskite.
