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.

Perovskite film, precursor composition thereof, method for preparing the same, and semiconductor element including the same

A dye adsorption method and a dye adsorption apparatus is provided in this disclosure. The dye adsorption method includes a dye adsorption step. In the dye adsorption step, a dye is injected into and flowed through a space between two electrodes of a solar cell facing each other to obtain at least one dye-adsorbed electrode.
