Organic-Inorganic hybrid solar cells have been made to explore potential applications. When inorganic semiconductors introduced in organic photoactive layer, they can affect to controlling optical and structural characteristics through expansion of absorption region and conformation of crystalline structure. Quantum dots (QDs) are attractive inorganic semiconductors for modified photoactive layer based on their unique properties. Among QDs, core@shell QDs have recently received attention for their ability to improving quantum yield. In this study, hybrid solar cells with polymer and core@shell QDs were fabricated via solution process. When core@shell QDs introduced in photoactive layer, they absorbed near-ultraviolet and visible wavelength, and transferred photon energy to polymers with high quantum yield by means of changing crystalline structure of the hybrid active layer. As a results, photovoltaic performance was enhanced. |
