<P>PROBLEM TO BE SOLVED: To provide a photovoltaic power generation apparatus which has improved transfer accuracy, can suppress damage due to dust or the like, and has a fine uneven structure of a submicron size, and to provide a manufacturing method therefor. <P>SOLUTION: A photovoltaic power generation apparatus 1 comprises: a transparent substrate 2 having an incident face 2A on which sunlight L is made incident and an emission face 2B which emits the sunlight L that has been made incident on the incident face 2A, and is arranged so as to face the incident face 2A; and a transparent electrode 3, photoelectric conversion layers 4 to 6, and a reflection electrode 8, which are sequentially formed on the emission face of the transparent substrate 2. A fine uneven structure 10 having a plurality of conical shape parts which have a height of 300 nm or less, and an aspect ratio of the height with respect to a bottom face of one or more, is formed on the incident face 2A and the emission face 2B. A columnar projecting part 90 having a height 100 times or higher than the height of the conical shape part is further formed on the incident face 2A. <P>COPYRIGHT: (C)2012,JPO&INPIT |
