<P>PROBLEM TO BE SOLVED: To provide an inexpensive condensing-type solar cell having high energy conversion efficiency which improves dissipation of heat from the solar cell when sunlight is condensed with a high magnification, and can be manufactured without increasing the size of a manufacturing apparatus. <P>SOLUTION: When sunlight is condensed by a condenser lens, chromatic aberration is generated due to the difference of refractive index of each wavelength. The chromatic aberration range of a wavelength band corresponding to the bandgap of each individual solar cell element in a solar cell can be expanded in plane, and the solar cell elements are arranged in that chromatic aberration range. According to this method, solar cells having many kinds of bandgap can be manufactured without requiring lamination. <P>COPYRIGHT: (C)2012,JPO&INPIT |
