摘要:
A thin-film solar cell having a hetero-junction of semiconductor and the fabrication method thereof are provided. Instead of the conventional hetero-junction of III-V semiconductor or homo-structure of IV semiconductor, the thin-film solar cell according to the present invention adopts a novel hetero-junction structure of IV semiconductor to improve the cell efficiency thereof. By adjusting the amount of layer sequences and the thickness of the hetero-junction structure, the cell efficiency of the thin-film solar cell according to the present invention is also optimized.
