Abstract
A method for preparing a perovskite film includes the steps of applying a first solution on a substrate to form a film by spin coating and applying a second solution on the film made from the first solution by spin coating to form the perovskite film. The perovskite film is expressed by a general formula of ABX. The solute of the first solution at least contains one of AX and BX. The solute of the second solution at least contains one of AX and BX. A method for preparing the solar cell using the perovskite film as the active layer (absorber) is also disclosed.
