<p><P>PROBLEM TO BE SOLVED: To provide a photovoltaic power generator such that a light condensing portion which condenses light on a photoelectric converting portion is reduced in vertical length, and to provide a method of manufacturing the photovoltaic power generator. <P>SOLUTION: The photovoltaic power generator includes: the photoelectric converting portion 11 which extends linearly; and the light condensing portion 30 which extends in a columnar shape so as to condense light on the photoelectric converting portion 11. The light condensing portion 30 has: an upper surface 31 which receives light and allows the light to pass; a first side surface 32 which extends obliquely from an edge of the upper surface 31 so as to includes the upper surface 31 when being seen through from above, and reflects light passing through the upper surface 31; a second side surface 33 which faces the first side surface 32 and also extends obliquely along the first side surface 32, and reflects light reflected by the first side surface 32; and a lower surface 34 which faces the photoelectric converting portion 11 and allows light reflected by the second side surface 33 to pass so as to guide the light to the photoelectric converting portion 11; wherein the first side surface 32 has a portion curved so as to condense light on the photoelectric converting portion 11 through the second side surface 33. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
