Abstract: A solar cell with an anti-reflection structure comprises a solar cell substrate, a meshed electric-conduction layer formed on one surface of the solar cell substrate, a plurality of microspheres disposed on the meshed electric-conduction layer, and a dielectric layer. The microspheres have a diameter of 0.1-50 ?m. The dielectric layer is formed between the meshed electric-conduction layer and the microspheres, and has a thickness smaller than the diameter of the microspheres to make the microspheres protrude from the dielectric layer. The meshed electric-conduction layer is formed via a screen-printing method. The present invention uses the microspheres and the meshed electric-conduction layer to achieve an excellent anti-reflection effect. Further, the present invention has the advantages of a simple fabrication process and a low fabrication cost.

Abstract: The present invention discloses a solar cell integrating monocrystalline silicon and a SiGe film, which comprises an N-type amorphous silicon-germanium (SiGe) film formed on a P-type monocrystalline silicon substrate. The P-type monocrystalline silicon substrate has a roughened surface to capture sunlight. A transparent conductive layer is stacked on the N-type amorphous SiGe film. Metal electrodes are formed on the transparent conductive layer and penetrate the transparent conductive layer to contact the N-type amorphous SiGe film. A P-type polycrystalline SiGe film is formed on the backside of the P-type monocrystalline silicon substrate. A back surface field is arranged below the P-type polycrystalline SiGe film to prevent from the recombination of major carriers. A backside metal electrode layer is arranged below the back surface field to function as a backside electrode and decrease the contact resistance. Thereby, the present invention can effectively promote the absorption rate of solar energy.
