    • A solar cell and a method of manufacturing the same are disclosed. The method includes simultaneously forming a first doping region of a first conductive type and a second doping region of a second conductive type opposite the first conductive type into a substrate of the first conductive type, forming a back passivation layer on the first doping region and the second doping region, removing portions of the back passivation layer to expose a portion of the first doping region and a portion of the second doping region, and forming a first electrode and a second electrode that are connected to the exposed portion of the first doping region and the exposed portion of the second doping region, respectively.
    • 公开了一种太阳能电池及其制造方法。 该方法包括同时形成第一导电类型的第一掺杂区域和与第一导电类型相反的第二导电类型的第二掺杂区域到第一导电类型的衬底中,在第一掺杂区域上形成反钝化层, 去除所述背面钝化层的部分以暴露所述第一掺杂区域的一部分和所述第二掺杂区域的一部分,以及形成连接到所述第一掺杂区域的暴露部分的第一电极和第二电极, 和第二掺杂区域的暴露部分。
