<p><P>PROBLEM TO BE SOLVED: To provide a light transmissive electrode achieving both of high generating efficiency and high transmittance, and a method of manufacturing the light transmissive electrode. <P>SOLUTION: A solar cell is equipped with: a photoelectric conversion layer; a light incidence surface side electrode layer; and a counter electrode layer. 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 the whole transmittance is 5% or more at 700 nm. The light incidence surface side electrode layer of this solar cell can be formed by etching using a single particle layer of fine particles and dot patterns of a self-organization of a block copolymer as a mask, and by utilizing a stamper. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
