Embodiment Construction
[0022] see figure 1 , the nano-silicon thin film double-junction solar cell of the present invention comprises a positive electrode layer 1 and a negative electrode layer 3, and three P-I-N junctions (subcells) 21, 22 and 23 are arranged between the positive electrode layer 1 and the negative electrode layer 3 as photoelectric In the conversion layer, the P-I-N junction 21 is the top cell, and the P-I-N junction 23 is the bottom cell. The P-I-N junction 21 is composed of a P-type silicon film layer 211, an intrinsic silicon film absorbing layer 212 and an N-type silicon film layer 213, and the P-I-N junction 22 is composed of a P-type silicon film layer 221, an intrinsic silicon film absorbing layer 222 and an N-type silicon film layer. The silicon thin film layer 223 is stacked in sequence, and the P-I-N junction 23 is composed of a P-type silicon thin film layer 231, an intrinsic silicon thin film absorption layer 232 and an N-type silicon thin film layer 233.
