  • Publication number: 20100101641
    Abstract: A solar cell coating and a method for manufacturing the solar cell coating. The solar cell coating is formed by adding a low bandgap material, a semiconductor material and a conductive polymer to a solvent or performing high-temperature milling on a mixture formed by mixing a conductive polymer material, a low bandgap material and a semiconductor material so that the solar cell coating exhibits high capability in transporting carriers effectively to transmit the electrons and holes to respective electrodes rapidly. Since the low bandgap material exhibits a small bandgap, MEG takes place to generate a plurality of electro-hole pairs when a photon is absorbed by the low bandgap material. Besides, by mixing the three materials corresponding to different conductive and valence bands respectively, a ladder structure formed by the HOMO and the LUMO corresponding to the three materials respectively will assist effective and rapid carrier transport.
