Abstract

The invention discloses a method for preparing a Sb2S3-base organic and inorganic composite solar cell. According to the method for preparing the Sb2S3-base organic and inorganic composite solar cell, nanopore titanium dioxide thin films which are ordered in height are prepared through a superheated steam method, titanium dioxide thin film pore ducts which are ordered in height are used as a template for Sb2S3 particles to grow, and therefore ordered growth of Sb2S3 nanometer crystals can be guaranteed, and stability of the solar cell can be effectively guaranteed; the Sb2S3 nanometer crystals are prepared through a chemical bath method and has the nanoscale size, the average particle size is about 5nm, the Sb2S3 nanometer crystals rank in order, and therefore transmission of electrons is facilitated; the organic and inorganic composite solar cell is manufactured through a spin coating method. The acquired Sb2S3-base organic and inorganic composite solar cell is compact in structure and has the good photoelectric conversion rate and stability; due to the fact that reservoirs of antimony elements and sulphur elements in the earth crust are rich, production cost of the solar cell is greatly reduced.
