SOLAR CELL AND METHOD FOR PREPARING SAME

摘要

Provided are a solar cell and a method for preparing the same. The solar cell comprises a transparent substrate (5), a transparent conductive thin film layer (4), a silicon thin film layer (31), a carbon nanotube thin film layer (2) and a back electrode (1) laminated in sequence. The silicon thin film layer (31) is formed by at least two layers of silicon thin films (311, 312), and the silicon in the silicon thin film layers (311, 312) is amorphous silicon or microcrystalline silicon. The silicon thin film layer (31) forms a heterogeneous junction with the carbon nanotube thin film layer (2).
