The invention relates to the technical field of solar energy, particularly a solar cell. The amorphous silicon solar cell based on a bifacial metal cladding waveguide structure comprises a solar cell layer, wherein the solar cell layer comprises a substrate layer, an amorphous silicon layer, a conducting film layer and a glass layer, wherein the glass layer, the conducting film layer and the amorphous silicon layer form a waveguide layer; the substrate layer adopts a metal total reflection layer; a metal coupling layer is arranged on the glass layer; and the metal coupling layer, the waveguide layer and the metal total reflection layer form a waveguide structure. The manufacturing method comprises the following steps: 1) preparing the glass layer; 2) preparing the mask; 3) preparing the metal coupling layer; 4) preparing the conducting film layer; 5) preparing the amorphous silicon layer; and 6) preparing the metal total reflection layer. Due to the technical scheme above, the invention has the advantages of
