Colloidal semiconducting nanocrystals have been identified as a set of promising and versatile nanostructured building blocks for numerous applications owing to their many attractive merits. While colloidal cadmium and lead chalcogenide nanocrystals have been widely explored for use in a variety of photonic and optoelectronic applications, consideration of the environmental compatibility and earth abundance of the materials has motivated the expansion of the research into environmentally friendly and earth-abundant colloidal semiconducting nanocrystals. The most common non-toxic semiconducting materials that have been extensively studied for photovoltaic applications include iron disulfide (FeS2), copper(I) sulfide (Cu2S), tin sulfide (SnS), tin selenide (SnSe), bismuth sulfide (Bi2S3), as well as ternary and quaternary copper chalcogenides such as copper zinc tin sulfide (Cu2ZnSnS4, CZTS). This feature study highlights the recent advances in colloidal synthetic procedures for FeS2, Cu2S, SnS, SnSe, Bi2S3, and CZTS nanocrystals, followed by examples from the literature of how these materials have been utilized in photovoltaic devices. The scientific challenges associated with the syntheses of these environmentally friendly and earth-abundant colloidal chalcogenide nanocrystals and the prospects for their deployment in photovoltaic applications have also been discussed.

环保且富含地球的胶体硫属元素化物纳米晶体,用于光伏应用

胶体半导体纳米晶体由于具有许多吸引人的优点,已经被确定为一组有前途且用途广泛的纳米结构构建基块,可用于许多应用。胶态镉和硫族化物铅纳米晶体已广泛用于各种光子和光电应用中,但考虑到材料的环境相容性和地球丰度,促使人们将研究扩展到环保和地球上富集的胶态半导体纳米晶体。广泛用于光伏应用的最常见的无毒半导体材料包括二硫化铁(FeS 2),硫化铜(I)(Cu 2S),硫化锡(SnS),硒化锡(SnSe),硫化铋(Bi 2 S 3)以及三元和四元铜硫属元素化物,例如硫化铜锌锡(Cu 2 ZnSnS 4,CZTS)。该特征研究突出了FeS 2,Cu 2 S,SnS,SnSe,Bi 2 S 3的胶体合成工艺的最新进展。,以及CZTS纳米晶体,随后是文献中如何在光伏器件中利用这些材料的示例。还讨论了与这些环境友好和地球上丰富的胶体硫属化物纳米晶体的合成相关的科学挑战,以及它们在光伏应用中的部署前景。
