Abstract

The invention discloses a method for preparing FeS2 / In2S3 composite membrane. An ITO membrane conductive glass substrate is electrodeposited with precast membrane by being merged in a water solution whose molar concentration ratio of 1: 5 to 6, and then is oxidized in 130 to 180 DEG C. to obtain porous Fe3O4 / In2O3 composite precursor membrane, and then is vulcanized in a condition of 400 DEG C. and 40 to 80 kPa sulphur vapour nominal pressure for 10 to 30 hours to convert the composite precursor membrane into a FeS2 / In2S3 composite membrane. The invention adds oxidation process after the electrodeposition process thereby accelerating the FeS2 reaction in heat vulcanization so as to directly form In2S3 by vulcanizing the substrate membrane, in this manner, the process for independently synthesizing In2S3 can be left out, and the bound of FeS2 / In2S4 two phase interfaces can be effectively guaranteed, the composite membrane is tightly and reliably adhibited on the substrate.

Description

technical field [0001] The invention belongs to the field of materials and relates to the preparation of functional materials, specifically a solar cell material FeS 2 / In 2 S 3 Preparation method of composite membrane. Background technique [0002] With the advancement of science and technology and the development of human civilization, primary energy sources such as coal, oil and natural gas are increasingly unable to meet the needs. Moreover, a large amount of harmful gas will be released during the use of disposable energy, which will destroy the environment on which human beings live. Therefore, among various renewable resources, solar energy has become the focus of new energy utilization and development. One of the main forms of development is to effectively convert sunlight energy into electrical energy for the benefit of mankind. [0003] A solar cell is an effective device that directly converts light energy into electrical energy, and the photoelectrode materia...
