<P>PROBLEM TO BE SOLVED: To provide a dye-sensitized solar cell capable of converting incident light into electric energy by efficiently absorbing (utilizing) it. <P>SOLUTION: The dye-sensitized solar cell 1 has a first anode 10 having a first sensitizing dye 24 and a second anode 30 having a second sensitizing dye 44 different from the first sensitizing dye arranged separated in front and rear direction. A cathode 50 (typically mesh electrode) is arranged between both anodes 10, 30. By these electrodes 10, 30, 50, a solar cell 1 in which two sub cells 6, 7 connected electrically in parallel are superposed in front and rear is formed. Thereby, light L2 which has transmitted through the first anode 10 is introduced efficiently into the second anode 30 and furthermore, energy can be taken out from the light L2. <P>COPYRIGHT: (C)2008,JPO&INPIT |
