    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.
