Effect of Solvent Environment on Colloidal-Quantum-Dot Solar-Cell Manufacturability and Performance (original) (raw)

This research examines the impact of solvent environments on the manufacturability and efficiency of colloidal quantum dot (CQD) solar cells. A focus on ligand exchange processes reveals that the commonly used layer-by-layer (LbL) method presents limitations in scalability and efficiency, particularly in reducing the steps needed for construction. By implementing alternative approaches, including a solution-phase ligand exchange strategy, the study finds that while significant performance improvements can be achieved, challenges such as charge carrier traps and optimal ligand coverage remain pertinent issues, thereby informing future strategies for enhancing the performance of CQD solar cells.
