Light absorber is critical to the further applications of thin film solar cells. Here, we report a facile solution-processed method with an annealing temperature below 250°C to fabricate Ag8SnS6 (ATS) light absorber for thin film solar cells. After optimization, the ATS-based thin film solar cells exhibited a reproducible power conversion efficiency (PCE) of about 0.25% and an outstanding long-term stability with 90% of the initial PCE retained after a more than 1,000 h degradation test. This research revealed the potential application of ATS as an earth-abundant, low toxic and chemically stable light absorber in thin film solar cells.

吸光材料是薄膜太阳电池进一步应用的重要因素. 三元硫化物Ag8SnS6 (ATS)拥有诸多优秀的光电性质. 然而, 关于ATS在吸光材料方面的应用鲜有报道. 因此, 本文通过使用一种退火温度低于250°C的温和溶液法制备ATS吸光材料并将其应用于薄膜太阳电池之中. 在优化之后, 基于ATS的薄膜太阳电池展现出了具有潜力的光伏性能以及可再现的0.25%光电转化效率. 更重要的是, 基于ATS的器件展现出了卓越的长期稳定性, 在超过1000小时的老化测试后器件仍然还有90%的初始效率. 本研究不仅揭示了含量丰富、 低毒且化学性质稳定的ATS作为吸光材料的潜力, 也为薄膜太阳电池中新型吸光材料的研究提供了全新的视角.
