- Abstract:
-
This thesis examines the effect of lead sulphide (PbS) CQDs’ surface chemistry and interfaces to their photovoltaic performance.
Using PbS CQDs as the starting material, cation-exchange was utilised to form PbS/CdS core/shell CQDs, which were thoroughly characterised and the improved surface passivation was shown by increased photoluminescence yield and lifetime. The core/shell CQDs were incorporated into a ZnO/CQD heterojunction solar cell device and showed a substantial improveme...
