    摘要: One embodiment of the present invention provides a solar cell with shade-free front electrode. The solar cell includes a photovoltaic body, a front-side ohmic contact layer situated above the photovoltaic body, a back-side ohmic contact layer situated below the photovoltaic body, a front-side electrode situated above the front-side ohmic contact layer, and a back-side electrode situated below the back-side ohmic contact layer. The front-side electrode includes a plurality of parallel metal grid lines, and the surface of at least one metal grid line is curved, thereby allowing incident light hitting the curved surface to be reflected downward and absorbed by the solar cell surface adjacent to the metal grid line.

    摘要: One embodiment of the present invention provides a method for fabricating a solar cell. The method includes: melting a metallurgical-grade (MG) Si feedstock, lowering a single-crystalline Si seed to touch the surface of the molten MG-Si, slowly pulling out a single-crystal Si ingot of the molten MG-Si, processing the Si ingot into single crystal Si wafers to form MG-Si substrates for subsequent epitaxial growth, leaching out residual metal impurities in the MG-Si substrate, epitaxially growing a layer of single-crystal Si thin film doped with boron on the MG-Si substrate, doping phosphor to the single-crystal Si thin film to form an emitter layer, depositing an anti-reflection layer on top of the single-crystal Si thin film, and forming the front and the back electrical contacts.
