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 μm. 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.
