摘要： The present invention provides a light transmission type solar cell excellent in both power generation efficiency and light transparency, and also provides a method for producing that solar cell. The solar cell of the present invention comprises a photoelectric conversion layer, a light-incident side electrode layer, and a counter electrode layer. The incident side electrode layer is provided with plural openings bored through the layer, and has a thickness of 10 nm to 200 nm. Each of the openings occupies an area of 80 nm2 to 0.8 μm2, and the opening ratio is in the range of 10% to 66%. The transmittance of the whole cell is 5% or more at 700 nm wavelength. The incident side electrode layer can be formed by etching fabrication with a stamper. In the etching fabrication, a mono-particle layer of fine particles or a dot pattern formed by self-assembled block copolymer can be used as a mask.
