DRIVE
August 25, 2004
The object of the present invention is to provide a light absorptive composition which exerts an improved photoelectric conversion efficiency in photoelectric conversion elements such as solar cells. The present invention attains the above object by providing a light absorptive composition, which comprises a first organic compound that absorbs light with a wavelength ranging from the ultraviolet region to the visible region to emit light with a longer wavelength than that of the absorbed light, and a second organic compound that absorbs the light emitted from the first organic compound; a semiconductor electrode which has been sensitized with the light absorptive composition; a photoelectric conversion element comprising the light absorptive composition; and a solar cell comprising the light absorptive composition.
