SpletHere we demonstrate solar cells made from PbS–CdS core–shell QDs, yielding a 147 mV increase in VOC compared to core only PbS QDs. We explore the physical reason for this enhancement and demonstrate that it is indeed caused by improved passivation of the PbS surface by the CdS shell, leading to a lower electron trap density. 收回
