The utility model relates to a device which uses dye or dyestuffc photosensitizers that absorb visible light intensity to broaden the spectral response of semiconductors so as to convert light energy into electric energy. The dye or dyestuffc sensitizer adsorbed on the semiconductor surface matches the energy level of the semiconductor. When the dye or dyestuffc sensitizer is illuminated, an electron hole pair is generated, and then a charge is injected into the semiconductor to realize charge separation. Output photocurrent and photovoltage externally. Most semiconductor materials used in dye sensitized solar cell are wide bandgap semiconductor materials with narrow spectral response, while dye or dyestuffc sensitizer uses organic dye or dyestuffc molecules and inorganic dye or dyestuffc molecules with wide spectral response.
