The invention discloses a solar cell with a high conversion rate, which comprises a substrate, wherein the substrate is provided with a first conductive layer, the substrate is provided with a P+ amorphous silicon layer at one side of the first conductive layer, the P+ amorphous silicon layer is provided with an intrinsic amorphous silicon layer at the side away from the first conductive layer, the intrinsic amorphous silicon layer is provided with an N+ amorphous silicon layer at the side away from the P+ amorphous silicon layer, and the N+ amorphous silicon layer is provided with a protective layer at the side away from the intrinsic amorphous silicon layer. According to the invention, multi-layer laminated structures such as a three-layer P-i-N laminated structure are manufactured or some transition layers are inserted in order to improve the efficiency and the stability, wherein the intrinsic amorphous silicon layer is the i layer which is used for improving the photoelectric conversion efficiency and stability of the solar cell with an amorphous silicon structure. In addition, the thickness of the amorphous silicon solar cell is only 1% of that of monocrystalline silicon or polycrystalline silicon, which can well absorb the sunlight. A lot of materials are saved so as to reduce the manufacturing cost of the solar cell, and the photoelectric conversion efficiency of the solar cell is improved at the same time.
