Abstract

The invention relates to a Si-PEDOT:PSS organic-inorganic hybrid solar cell and a preparation method thereof. The method comprises the texturing treatment of an n-type single crystal silicon wafer; a metal copper barrier layer is provided and heat treatment is carried out in an oxygen-containing atmosphere, so that The doping concentration of the surface of the second region in the n-type single crystal silicon wafer is lower than the doping concentration inside the n-type single crystal silicon wafer; the metal copper barrier layer and the silicon oxide layer are removed; first, The preparation of the second and third PEDOT:PSS layers; the preparation of the front gate electrode; the preparation of the lithium fluoride thin layer and the back electrode. The Si-PEDOT:PSS organic-inorganic hybrid solar cell prepared by the invention has excellent performance.

Description

technical field [0001] The invention relates to the technical field of hybrid solar cells, in particular to a Si-PEDOT:PSS organic-inorganic hybrid solar cell and a preparation method thereof. Background technique [0002] Solar energy can be said to be "inexhaustible and inexhaustible" energy. Compared with traditional petrochemical energy, solar energy has unique advantages such as green, clean and renewable. Converting solar energy into electrical energy is an important technical basis for the widespread use of solar energy. The conversion methods include indirect photothermal conversion and direct photoelectric conversion. The latter mainly refers to solar cells. Existing silicon-based solar cells include monocrystalline silicon solar cells, polycrystalline silicon solar cells, microcrystalline silicon solar cells, amorphous silicon thin-film solar cells and silicon-based organic-inorganic hybrid solar cells, wherein silicon-based organic-inorganic hybrid solar cells It...
