<p><P>PROBLEM TO BE SOLVED: To provide a solar battery which uses light more efficiently by letting external light such as the sun light into a solar battery element efficiently. <P>SOLUTION: The solar battery comprises a solar battery element having a photoelectric transfer layer 2, a group 4 of cylindrical condensing curved surfaces, and a condensing element 3 which has a group 7 of linear light passage holes which pass light through so that the sun light 8 condensed by the group 4 of cylindrical curved surfaces can be incident into the solar battery element. In the condensing element 3, a first light reflection tilted surface 5 and a second light reflection tilted surface 6 reflect light in the condensing element and lead the reflected light to the group 7 of the linear light passage holes, and are grouped with each one of the linear light passage holes 7. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
