<P>PROBLEM TO BE SOLVED: To provide a photoelectric conversion element which is capable of improving power generation efficiency, and a method for manufacturing the same. <P>SOLUTION: A solar cell 1 comprises a substrate 10 having a three-dimensional structure 10A composed of a microstructure formed by arranging a plurality of protrusions and a nanostructure formed on a surface of the microstructure. A light-receiving element 11 is provided on a surface of the substrate 10. That surface of a transparent electrode 12 of the light-receiving element 11 which is opposite to the substrate 10 has a three-dimensional structure 11A following the three-dimensional structure 10A. In a photoelectric conversion layer 13, incident light is effectively absorbed by the microstructure, and a current density is increased by electric field concentration due to the nanostructure. A generated current is efficiently extracted. <P>COPYRIGHT: (C)2012,JPO&INPIT |
