New Approaches to Quantum Dots for Solar Cell Applications

Abstract

Quantum dots (QDs) have emerged as a promising material for enhancing the efficiency of solar cells, thanks to their tunable electronic properties, high surface-area-to-volume ratio, and ability to absorb and emit light in a size-dependent manner. This article reviews the latest advancements in the application of quantum dots in solar cell technologies, focusing on their integration into perovskite and organic photovoltaics. We explore the improvements in power conversion efficiency (PCE) brought about by quantum dot incorporation, as well as the challenges of scalability, stability, and toxicity. Novel surface engineering techniques, tandem cell configurations, and material innovations are also discussed in light of their potential to revolutionize the photovoltaic industry.
