摘要
Abstract
In this paper,the preparation of Li doped in CZTSSe films by sol-gel method based on di-methyl sulfoxide solvent system was carried out.The surface morphology,crystal structure and com-position ratio of CZTSSe films with different Li doping levels were tested respectively.The results showed that the crystal quality of CZTSSe films could be improved by Li doping,and the crystal quality became better with the increase of Li doping amount.The reason is that the Li2Se phase as-sisted growth during high temperature selenization can improve the crystal quality of the films and inhibit the formation of donor level defects such as ZnCu and SnCu.However,there is a Li doping threshold between 1%and 10%Li/Cu,and excess Li cannot enter the lattice and is enriched at the grain boundary.The results show that the solar cell with 1%Li/Cu has the highest conversion effi-ciency,reaching 8.5%.关键词
