Application of additive, formamidinium iodide and preparation method therefor, perovskite solar cell, solar power generation apparatus, and electrical apparatus

Abstract

An additive, formamidinium iodide and a preparation method therefor, a perovskite solar cell, a solar power generation apparatus, and an electrical apparatus. The additive includes a reducing agent. By incorporating the reducing agent in the additive and using the additive to prepare formamidinium iodide, generation of elemental iodine in the preparation process of formamidinium iodide can be reduced; in addition, iodine which has been oxidized to elemental iodine can be reduced to iodine anions so as to generate formamidinium iodide. The stability of formamidinium iodide is improved, and thus the stability and efficiency of perovskite cells are improved.
