摘要

Polymer-inorganic nanocrystal hybrid solar cells have drawn considerable attentions as one of the promising renewable energy sources.1-3 The photoactive layer of these polymer-inorganic hybrid cells comprises an interpenetrating network of two phases – electron donor, and electron acceptors. Electron donor materials are usually conducting conjugated polymers, for example, regioregular poly(3- hexylthiophene) (P3HT), whereas electron acceptor materials are usually semiconducting, inorganic nanocrystals such as CdSe, ZnO, PbS, and TiO2.1 These hybrid solar cells have advantages over their pure inorganic counterpart, because of their lower production cost from solution processing, mechanical flexibility, light-weight, and additional flexibilities provided by controlling the shape and sizes of inorganic nanocrystals. A number of novel inorganic nanocrystal shapes with controllable sizes have been synthesized; these nanostrutural materials have significant impacts on the organization of both electron donor and acceptor materials, and on the electronic properties of electron acceptor materials, potentially helping improve the efficiency of polymer-inorganic hybrid solar cells.
