Abstract
The invention relates to a method for preparing a formamidino FAPbI3 perovskite solar cell at medium and low temperature in air and application, and belongs to the field of optoelectronic materials and devices. The preparation method comprises the following steps: dissolving lead iodide and iodoformamidine in a stoichiometric ratio of 1: 1 in a protic ionic liquid solution to prepare a perovskite precursor solution, and stirring and reacting at the high temperature of 90 DEG C for 36 hours; in the air, the precursor solution is respectively spin-coated on an ITO or FTO conductive substrate with a hole transport layer or an electron transport layer through a one-step heating spin-coating technology, and the conversion of the black-phase perovskite can be realized at normal temperature. And then spin-coating an electron transport layer or a hole transport layer on the thin film, and evaporating a modification layer and a metal Ag electrode by using a vacuum evaporation technology.
