摘要

我们采用低毒性分子前驱体溶液法在低温下制备了紧凑光滑的纳米晶 CuInS2 薄膜，其带隙约为 1.5 eV，有望用于光伏领域。我们制作了一种平面异质结太阳能电池，其配置为 FTO/CdS/CuInS2/Spiro-OMeTAD/Au。在 350 °C 下退火的 CuInS2 薄膜冠军器件的平均功率转换效率为 1.79%（最高 1.94%），并表现出良好的稳定性。

A low-toxicity molecular precursor for nanocrystalline CuInS2 solar cells

Compact and smooth nanocrystalline CuInS₂ thin films were prepared by a low-toxicity molecular precursor solution method at low-temperature and exhibit band gaps of about 1.5 eV, which is promising for photovoltaics. We fabricated a planar heterojunction solar cell configured as FTO/CdS/CuInS₂/Spiro-OMeTAD/Au. The champion device based on CuInS₂ film annealed at 350 °C yields an average power conversion efficiency of 1.79 % (maximum 1.94 %) and exhibits a good stability.
