<p><P>PROBLEM TO BE SOLVED: To propose constitution of an optimum pin junction of a photoelectromotive force element which has high conversion efficiency, can be manufactured at a low cost, and is lightweight and totally superior. <P>SOLUTION: A thin-film photoelectromotive force element is constituted by providing an antireflective layer 119, a plurality of pin junctions 104 to 118, and reverse-surface reflecting layers 102 and 103 having an 0.1 to 10μm uneven surface shape in order in series from a light incidence side. The plurality of pin junctions comprise pin junctions 113 to 118 with two series-connected (i) type amorphous semiconductors, having a≤0.8μm total thickness, and pin junctions 104 to 112 with three series-connected (i) type fine crystal semiconductors, having a≤8.0μm total thickness, namely. five pin junctions in total being connected in series. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
