Abstract
Provided is a perovskite film including crystal grains with a crystalline structure of [A][B][X].n[C], wherein [A], [B], [X], [C] and n are as defined in the specification. The present disclosure further provides a precursor composition of perovskite film, method for producing of perovskite film, and semiconductor element including such films, as described above. With the optimal lattice arrangement, the perovskite film shows the effects of small surface roughness, and the semiconductor element thereof can thus achieve high efficiency and stability even with large area of film formation, thereby indeed having prospect of the application.
