<p><P>PROBLEM TO BE SOLVED: To easily enhance power generation performance per unit area of a solar cell even if the light receiving surface of the solar cell is not irradiated uniformly with sunlight by condensing the sunlight to be received on the light receiving surface of the solar cell. <P>SOLUTION: Even if the irradiation angle of sunlight to a lens 2 is shifted as shown by a dot line, the sunlight received on the light receiving surface of the solar cell 1 through condensation via the lens 2 simply moves on the light receiving surface of the solar cell 1, and the current to be delivered to a step-up circuit from a solar cell 1 receiving the sunlight condensed via the lens 2 becomes the total sum of output currents from respective solar cells 1. This is similar to the case where the near center of the solar cell 1 is irradiated with sunlight. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
