Abstract:
Provided is a solar cell and a method for manufacturing the same, the method includes: forming a doped layer on a surface of a semiconductor substrate, the doped layer having a first doping concentration of a doping element in the doped layer; depositing, on a surface of the doped layer, a doped amorphous silicon layer including the doping element; selectively removing at least one region of the doped amorphous silicon layer; performing annealing treatment, for the semiconductor substrate to form a lightly doped region having the first doping concentration and a heavily doped region having a second doping concentration in the doped layer, the second doping concentration is greater than the first doping concentration; and forming a solar cell by post-processing the annealed semiconductor substrate. The solar cell and the method for manufacturing the same simplify the manufacturing process and improve conversion efficiency of the solar cell.
