Organic/inorganic metal halide formamidinium lead iodide (FAPbI3) perovskites exhibit excellent optical properties, a suitable band gap, a wide light-absorption range, and superior electron-hole mobility. However, it is difficult to fabricate high-quality α-phase FAPbI3 film due to the relatively easy formation of the more stable δ-FAPbI3 (hexagonal structure). To overcome this, in this study, formamidinium lead bromide (FAPbBr3) was used to induce the synthesis of stable α-phase FAPbI3. The resulting light-absorbing layer was composed of (FAPbI3)0.95 (FAPbBr3)0.05, but δ-phase FAPbI3 could be still observed. To suppress the formation of δ-phase FAPbI3 , methylammonium chloride (MACl) was added to the (FAPbI3)0.95 (FAPbBr3)0.05 precursor solution. At an optimal MACl content of 40 mol%, perovskites with improved crystallinity and large crystallite size could be fabricated, resulting in a perovskite solar-cell efficiency of 18.204%.

Anion/cation vacancies located at different interfaces in perovskite solar cells may modify the electronic energy landscape, hampering charge extraction, and presumably contributing to the observed J–V hysteresis.
