Abstract

The invention discloses a carbon nanotube-silicon film laminated solar battery and a preparation method thereof. The laminated battery solar battery comprises a transparent underlay, a transparent conductive film, a silicon film layer, a carbon nanotube film and a back electrode, which are sequentially laminated, wherein the silicon film layer consists of at least two layers of silicon films, and silicon in the silicon film layer is amorphous silicon or microcrystal silicon; and the silicon film layer and the carbon nanotube film form a heterojunction. The silicon film can be a positive-negative (PN) double-layer film, a positive intrinsic negative (PIN) three-layer film, a negative positive negative (NPN) three-layer film or a negative positive intrinsic negative (NPIN) four-layer film. In the film laminated battery, the carbon nanotube is used as a P+ layer and forms a laminated battery having a CNT / P+-P / N structure with the silicon film, the carbon nanotube and the silicon film form a laminated battery with a CNT / P+-P / I / N structure, with a CNT / P+-N / P / N structure or with a CNT / P+-N / P / I / N structure. The carbon nanotube-silicon film laminated battery can effectively improve the open-circuit voltage, the conversion efficiency and the like of the battery, and has the characteristics of simple process and low cost.

Description

technical field [0001] The invention relates to a carbon nanotube-silicon film laminated solar cell and a preparation method thereof. Background technique [0002] With the emergence of the energy crisis, people began to discover the importance of renewable energy, and renewable energy has become an issue that everyone pays more and more attention to. As one of the renewable clean energy sources, solar energy has been applied in various fields. Among them, the application of solar cells is particularly extensive, and the solar cells currently on the market are mainly based on silicon. Silicon solar cells are mainly divided into three types: monocrystalline silicon cells, polycrystalline silicon cells and amorphous (microcrystalline) silicon thin-film cells. Among them, silicon thin-film cells have the advantages of less material consumption, large area, low energy consumption, and low cost. to rapid development. At present, the photoelectric conversion efficiency of amorp...
