<P>PROBLEM TO BE SOLVED: To provide a solar cell having high utilization efficiency and high photoelectric conversion efficiency. <P>SOLUTION: A solar cell 1 is structured by forming a plurality of cylindrical lenses 8 on the surface (light incident face) of a base plate 2 so that the lenses stand adjacent to and parallel with one another, forming a V-shaped groove 10 on a back surface along the cylindrical lenses 8, laminating transparent electrodes 23 and semiconductor electrodes 5 sequentially on the back face, arranging the base plate 2 and an opposing electrode plate 3 so as to face each other, and by sealing electrolyte liquid 7 between both base plates. The lenses 8 are set so as to optically respond in a manner that incident light enters into edge faces 5A, 5B of the part bent at the grooves 10 of the electrodes 5 along the direction of the face of the electrodes 5. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
