Abstract:
Disclosed is a method for manufacturing a solar cell. The method for manufacturing a solar cell comprises the steps of: forming a transparent conductive layer on the upper part of a substrate; forming fine structures composed of a conductive metal oxide on the upper part of the transparent conductive layer; forming an electron delivering layer composed of an electron delivering metal oxide to cover the fine structures and the surface of the transparent conductive layer; adsorbing a light absorber to a pore and the surface inside the electron delivering layer; forming a hole transport layer composed of a hole transport material on the upper part of the electron delivering layer in which the light absorber is adsorbed; and forming an electrode on the upper part of the hole transport layer.
