<p><P>PROBLEM TO BE SOLVED: To provide a laminated photovoltaic element which efficiently collects energy over all the wavelength regions of incident light and has high conversion efficiency. <P>SOLUTION: The laminated photovoltaic element has at least a first photovoltaic element 105 and a second photovoltaic element 103 which are laminated in this order from the light incident side. A selection reflection layer 104 is provided between the first photovoltaic element and the second photovoltaic element so as to electrically connect the elements in series. Light having any one of wavelengths in a range of wavelengthsλm±100 nm produces resonance in the first photovoltaic element 105. The second photovoltaic element 103 has the maximum spectral characteristic in the range. <P>COPYRIGHT: (C)2004,JPO</p> |
