Organic-Inorganic hybrid solar cells are currently attracting a great attention due to ease of fabrication and potential of flexible device based on properties of polymers and some inorganic semiconductors. Among them, quantum dots (QDs) is attractive inorganic semiconductors for modified photoactive layer because of their broad light absorption property, size-dependent optical, electrical properties. Among QDs, size-distributed QDs have recently received attention for their ability to control bandgap energy be favored to energy transfer from QDs to polymers. In this study, hybrid solar cells with polymer and two size-distributed QDs were fabricated via solution process. When two size-distributed QDs introduced in photoactive layer, they absorbed near-ultraviolet and visible wavelength, and transferred photon energy to polymers with high quantum yield. As a result, photovoltaic performance was improved by increased Jsc, FF.
