Abstract 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.
A light absorptive composition, comprising a
first organic compound which 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 which absorbs the light
emitted from the first organic compound.
