Passivation Strategy of Reducing Both Electron and Hole Trap States for Achieving High-Efficiency PbS Quantum-Dot Solar Cells with Power Conversion Efficiency over 12%

Abstract

For the current passivation strategy, pure iodine passivation during solid-state ligand exchange (SSE) cannot completely passivate the entire surface of PbS colloidal quantum dots (CQDs). Here, a s...
