Bi2S3纳米晶体作为一种n型、无毒、无机、溶液处理的半导体应用于薄膜太阳能电池中。第一个基于p型PbS量子点和n型Bi2S3纳米晶体的溶液处理-无机p-n结，两相都有助于光载流子的产生。所报道的器件显示860 nm PbS量子点的功率转换效率为1.6%，1300 nm PbS量子点的功率转换效率超过1%。
Bi2S3 nanocrystals are employed as an n-type, non-toxic, inorganic, solution-processed semiconductor in thin film solar cells. The first solution processed-inorganic p-n junction based on p-type PbS QDs and n-type Bi2S3 nanocrystals with both phases contributing to photo-carrier generation is demonstrated. The reported devices show a power conversion efficiency of 1.6% for 860 nm PbS QDs and over 1% for 1300 nm PbS QDs.
