In this work we have incorporated MoS quantum dots having outstanding optoelectronic properties with methyl ammonium lead iodide (MAPI) to form a composite absorber material for photovoltaic applications. The inclusion of MoS quantum dots in the perovskite layer improves the absorption and charge transport properties of the active layer, in part due to the quantum dots contributing to defect passivation at the MAPI grain interfaces. The photocurrent density increases when the MoS quantum dots are introduced in the device structure, resulting in efficiency improvements of 14% and 28% for devices fabricated in different laboratories.
在这项工作中，我们将具有出色光电特性的二硫化钼量子点与甲基铵碘化铅（MAPI）相结合，形成用于光伏应用的复合吸收材料。在钙钛矿层中包含二硫化钼量子点可改善活性层的吸收和电荷传输特性，部分原因是量子点有助于在MAPI晶粒界面处实现缺陷钝化。当在器件结构中引入二硫化钼量子点时，光电流密度会增加，这使得在不同实验室制造的器件效率分别提高了14%和28%。
