Research Status and Development of CuInTe2 Thin Film Solar Cells

Abstract

Thin film solar cell is the best alternative to replace Si solar cell, which has the advantages of low cost, no pollution and so on. It has been developing rapidly in recent years. CuInTe2 thin-film battery which is similar to CIS thin-film battery belongs to Cu-AⅢ-BVI2 sulfur compounds. The energy gap of CuInTe2 are about 1.06eV, and it is a kind of good absorbing layer material. In this paper, the research history of the CuInTe2 thin film materials is briefly introduced. It only stays at the stage of preparation and performance testing, and has not been prepared for the finished battery at present. The feasibility and advantages of CuInTe2 as photoelectric material are explained from it’s structure characteristics. The advantages and disadvantages of various methods of preparing thin film materials are analyzed and impurities in the process are found in the progress. The optical properties and electrical properties of the CuInTe2 thin-film cells can be tested without the preparation of a battery due to the complexity of thin film solar cell structure.
