Method for manufacturing a solar cell

A method for manufacturing a solar cell includes: forming a first metal layer on a light receiving surface exposed from an anti-reflective layer opening of the photoelectric transformation substrate, and forming a second metal layer on a back surface exposed from an passivation layer opening of the photoelectric transformation substrate, wherein the first and second metal layers are formed simultaneously by a first eletroless plating process, and the first eletroless plating process is an eletroless plating process with high selectivity; and forming a third metal layer on the passivation layer, wherein the third metal layer is formed by a second eletroless plating process, and the second eletroless plating process is an eletroless plating process with low selectivity.
