摘要
半导体材料铜锌锡硫(Cu_2ZnSnS_4,CZTS)构成元素安全,无污染,而且含量丰富,所以其成本低廉,是绿色环保的新型纳米材料。其中,锌黄锡矿结构具有良好的稳定性,较高的吸收系数,且其吸收光谱与太阳光谱相似,符合制备太阳能电池所需的最佳禁带宽度,是符合绿色发展、性能优秀、极具潜力的薄膜太阳能电池材料。本文对采用CZTS纳米材料作为太阳能电池吸收层的电池结构、制备方法、应用前景等进行了分析讨论。
The semiconductormaterialCu2ZnSnS4(CZTS),Its constituent element is safe,pollution-free and environmentally friendly,andabundant in the earth,so its cost is low.It is a new type of green nanomaterials.Among them,the zinc-yellow-tin-ore structurehas good structural stability,high light absorption coefficient,and the band gap width of its absorption spectrum is similar to that of the solar spectrum.It is close to the optimal band gap width for preparing thin film solar cells.CZTS is in line with the green development,excellent performance,and great potential solar cell material.In this paper,the structure,preparation method,application and prospect of Cu2ZnSnS4 solar cell absorbeing was discussed.
