Provided are a HJT cell having high photoelectric conversion efficiency and a method for preparing the same. The HJT cell includes an N-type crystalline silicon wafer. An intrinsic amorphous silicon layer, a SiOlayer, a C-doped SiOlayer, a doped N-type amorphous silicon layer, a TCO conductive layer and an electrode are sequentially disposed on a front surface of the N-type crystalline silicon wafer. An intrinsic amorphous silicon layer, a SiOlayer, a C-doped SiOlayer, a doped P-type amorphous silicon layer, a TCO conductive layer and an electrode are sequentially disposed on a back surface of the N-type crystalline silicon wafer. The doped P-type amorphous silicon layer includes a lightly B-doped amorphous silicon layer and a heavily B-doped amorphous silicon layer.
