    摘要: A solar cell and a manufacturing method thereof are provided. A laser doping process is adopted to form positive and negative doping regions for an accurate control of the doping regions. No metal contact coverage issue arises since a contact opening is formed by later firing process. The solar cell is provided with a comb-like first electrode, a sheet-like second electrode corresponding to the doping regions to obtain high photoelectric conversion efficiency by fully utilizing the space in the semiconductor substrate. Furthermore, the sheet-like second electrode can be formed by a material having high reflectivity to improve the light utilization rate of the solar cell. The manufacturing process of the solar cell is simplified and the processing yield is improved.

    摘要: A method of fabricating a solar cell is provided. A first type substrate having a first surface and a second surface is provided. A first doping process is performed on the first surface of the first type substrate by using a first dopant, so as to form a first type lightly doped layer. A second doping process is performed on a portion of the first type lightly doped layer by using a second dopant, so as to form a second type heavily doped region. A molecular weight of the second dopant is larger than a molecular weight of the first dopant, and a temperature of the first doping process is higher than a temperature of the second doping process. A first electrode is formed on the second type heavily doped region. A second electrode is formed on the second surface of the first type substrate.

    摘要: A solar cell includes a semi-conductive substrate, a doping layer, an anti-reflection layer, an electrode, a passivation stacked layer and a contact layer. The semi-conductive substrate has a front and a back surface. The doping layer is disposed on the front surface. The anti-reflection layer is disposed on the doping layer. The electrode is disposed on the anti-reflection layer and electrically connected to the doping layer. The passivation stacked layer is disposed on the back surface and has a first dielectric layer, a second dielectric layer and a middle dielectric layer sandwiched between the first and the second dielectric layer. The dielectric constant of the middle dielectric layer is substantially lower than the dielectric constant of the first dielectric layer and the dielectric constant of the second dielectric layer. The contact layer covers the passivation stacked layer and electrically contacts with the back surface of the semi-conductive substrate.
