Hybrid Inorganic/Organic Photovoltaics: Translating Fundamental Nanostructure Research to Enhanced Solar Conversion Efficiency
Abstract
This is the report for a project to design and characterize conjugated oligomers/polymers and surface capping linkers for quantum dots, aimed towards facilitating the charge separation and enhancing the mobilities of carriers, which can lead to highly efficient quantum dot:carbon nanotubes: polymer nanocomposites based solar cells. These studies will significantly contribute to the understanding of efficient quantum-dot based solar cell architectures. The details are given below; - Preparation of various quantum dots, conjugated oligomers and polymers. - Enhanced broadband energy harvesting using engineered and surface functionalized semiconductor nanocrystals (quantum dots) of various sizes, shapes and compositions. - Enhanced exciton dissociation and minimized recombination via bandgap-engineered multicomponent hybrid nanocrystals through control of interfacial chemistry and linkage to other components. - Enhanced and balanced carrier mobility and efficient charge transfer through the incorporation of carbon nanotubes into organic matrices containing conjugated molecules. - Introduction of conjugated linker molecules for interconnection of inorganic nanocrystals and nanotubes for improved electron transfer between these nanoscale components.
