摘要: Water-dispersed CdSe/CdS/ZnS core/shell/shell quantum dots (QDs) with the highest yield of 25.4% were first synthesized for each component by microwave irradiation. As-prepared QDs do not only possess a large Stokes shift but also exhibit excellent repeatability. They can convert near UV and blue light lower sensitivity to Si solar cell red at which has higher sensitivity. The fabricated QDs/SiO2 composite films applied cells as luminescent down-shifting layers effect on photoelectric conversion efficiency photovoltaic modules was investigated. Under one sun illumination, film containing an appropriate amount effectively enhances spectral compared bare glass substrate, maximum achieves 16.14%.
