要約(英語): Organic thin-film solar cells based on P3HT and PCBM are widely utilized due to their stability in real-world environments. However, their efficiency remains limited by design constraints, such as thin active layers and significant light reflection in the visible spectrum. To address these challenges, enhanced light harvesting across both visible and UV regions is crucial. In this study, cadmium telluride quantum dots (CdTe QDs) were integrated at the interface between ITO glass and the hole transport layer using a spin-coating technique. CdTe QD concentrations ranging from 10?14 μM were evaluated, and photovoltaic performance was characterized. Interface effects, including surface morphology and electron transfer dynamics, were analyzed via AFM and impedance spectroscopy. The optimized configuration achieved a 6% increase in efficiency compared to the reference cells. Mechanistic insights were further explored using %IPCE analysis and DFT simulations.
