近年来化合物薄膜太阳电池得到迅猛的发展。SnS光电薄膜的禁带宽度与太阳光谱非常匹配,并且具有较高的吸收系数,所以它是一种理想的太阳电池材料。制备SnS光电薄膜的方法有电沉积法、热蒸发法、化学浴法、连续离子吸附沉积法、喷雾热解法和两步法等。不仅概述了不同掺杂元素以及掺杂浓度对SnS薄膜性能的影响,同时还讨论了目前国内外SnS薄膜太阳电池的研究状况,分析了当前SnS薄膜太阳电池效率偏低的原因。最后对SnS薄膜太阳电池的发展趋势与前景作了一些探讨。
In recent years, compound thin film solar cells have been rapidly developed. The band gap of SnS photoelectric film is very suitable for the solar spectrum and has a high absorption coefficient, so it is an ideal solar cell material. The preparation of SnS photoelectric thin film methods are electrodeposition, thermal evaporation, chemical bath, continuous ion adsorption deposition, spray pyrolysis and two-step method. The effects of different doping elements and doping concentration on the properties of SnS thin films are summarized. The research status of SnS thin film solar cells at home and abroad are also discussed. The reasons for the low efficiency of SnS thin film solar cells are analyzed. Finally, the development trends and prospects of SnS thin film solar cells are discussed.
