Solar cell metal electrode, preparation method thereof and solar cell

The invention provides a solar cell metal electrode, a preparation method thereof and a solar cell. The preparation method of the solar cell metal electrode comprises the following steps: fixing a patterned mask made of a polymer material on the surface of a substrate, and depositing metal on the surface of the substrate to grow a metal electrode with a required shape on the surface of the substrate, thereby obtaining the solar cell metal electrode. The invention also provides the metal electrode prepared by the method. The invention further provides a solar cell comprising the metal electrode. The method is low in manufacturing cost, and the prepared electrode is high in conductivity, small in shading area and high in photoelectric conversion rate. 本发明提供了一种太阳能电池金属电极及其制备方法与太阳能电池。本发明的太阳能电池金属电极的制备方法包括：将图案化的高分子材质的掩模版固定在基板的表面，然后向所述基板的该表面沉积金属以在所述基板的表面生长出所需形状的金属电极，得到所述太阳能电池金属电极。本发明还提供了上述方法制备得到的金属电极。本发明进一步提供了包含上述金属电极的太阳能电池。本发明的方法制作成本低，制备的电极导电率高、遮光面积小、光电转化率高。
