Inorganic Ligand Passivated PbS Colloidal Quantum dot Solar Cell via Solution-Phase Ligand Exchange Process |
| 초록 |
Quantum-dot (QD) photovoltaics (PVs) with easy band-gap tuning and broad absorption are promising candidates for future solar energy conversion system. Size of PbS QD which determines excitonic peak can be controlled by the injection temperature of hexamethyldisilathiane (TMS) during the synthesis. Then the oleic acid passivated PbS QD was completely exchanged to iodide passivated PbS QD using solution-phase ligand exchange method. We fabricated PbS QD PVs using iodide passivated PbS QD with various size and achieved high performance of 12.16% power conversion efficiency (PCE) using PbS QD with 910nm excitonic peak. |
