摘要
四元硫化物铜锌锡硫(CZTS)是一种新型薄膜太阳电池材料,具有锌黄锡矿结构,呈p型导电性,带隙约为1.5eV,光学吸收系数高于10~4cm^(-1),这些特性与太阳光谱相匹配。基于上述原因,CZTS薄膜是一种有望能低成本、可规模化开发利用的新型薄膜太阳电池材料。简要阐述了CZTS性质及其薄膜太阳能电池的器件结构,详细介绍了溶胶-凝胶方法制备CZTS薄膜及其相应器件效率的研究进展。最后,总结了此方法制备CZTS薄膜及其相关电池性能难以突破的关键技术问题,并提出了有效的改进措施,对CZTS薄膜太阳电池未来的研究进行了展望。
A quaternary chalcogenide-based compound Cu2ZnSnS4 (CZTS) is a novel material for thin film solar cell, possessing kesterite structure, p-type conductivity, a band gap energy of about 1. 5 eV and an absorption coefficient of higher than 10a^4cm^-1 , which match well with the solar spectrum. Based on the above masons, CZTS thin film is expected to be a new material for thin film solar cell, which can lower the cost and be developed and utilized in large scale. The property and device structure of CZTS thin film solar cell are elaborated. In addition, the preparation of CZTS thin film by sol-gel method and the research progress in the corresponding device performance are also investigated in detail. Finally, the key strategies of this technique, as well as the effective improvement measure are pointed out, and the future study direction of CZTS thin film solar cells is proposed.
