发明名称 Solar cell and method for manufacturing the same
摘要 A solar cell and a method for manufacturing the same are discussed. The solar cell includes a semiconductor substrate, a first doped region of a first conductive type, a second doped region of a second conductive type opposite the first conductive type, a back passivation layer having contact holes exposing a portion of each of the first and second doped regions, a first electrode formed on the first doped region exposed through the contact holes, a second electrode formed on the second doped region exposed through the contact holes, an alignment mark formed at one surface of the semiconductor substrate, and a textured surface that is formed at a light receiving surface of the semiconductor substrate opposite the one surface of the semiconductor substrate in which the first and second doped regions are formed.
