<p><P>PROBLEM TO BE SOLVED: To provide a solar cell which has both low resistance and high transmissivity and furthermore can efficiently utilize sunlight for excitation of a carrier and is equipped with a light incidence surface side electrode using inexpensive material, and to provide a method of manufacturing the solar cell. <P>SOLUTION: The solar cell is equipped with: a photoelectric conversion layer; a light incidence surface side electrode layer; and counter electrode layers. The light incidence surface side electrode layer is provided with a plurality of openings penetrating the light incidence surface side electrode layer, and a film thickness thereof is in a range of 10 nm or more and 200 nm or less, and an area per one opening of the openings is in a range of 80 nm<SP>2</SP>or more and 0.8μm<SP>2</SP>or less, and numerical apertures of the openings are in a range of 10% or more and 66% or less, and at least a part of a light absorbing layer is arranged at a distance of 1μm or less from a contact surface of the light incidence surface side electrode layer and the photoelectric conversion layer. The light incidence surface side electrode layer of this solar cell can be formed by etching using a single particle layer of fine particles or dot patterns of a self-organization of a block copolymer as a mask, or by utilizing a stamper. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
