<p><P>PROBLEM TO BE SOLVED: To miniaturize a system for controlling a solar cell so as to follow the movement of the sun. <P>SOLUTION: The solar cell 12 is constituted of laminating a solar cell panel 16, a display panel 18, a first elastic member 20, a bending plate 22, and a second elastic member 24. The solar cell panel 12 is transparent and a black-and-white image or a shielding pattern is shown on the display panel 18 in accordance with a time or an azimuth. The bending plate 22 is formed of a resin, which is bent when ultraviolet rays hit the same, and is capable of being bent freely by the first elastic member 20 and the second elastic member 24. The bending plate 22 is bent by ultraviolet rays penetrated through the non-display section of the display panel 18 to change the direction of a light receiving surface 16A for the solar cell panel 16. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
