A new type of water-soluble conjugated polymer composed of poly[(3,4-dibromo-2,5-thienylene vinylene)-co-(p-phenylene-vinylene)] (PBTPV) is synthesized. Its excellent film-forming properties, stability, and photoelectric response show good potential for organic field-effect transistor and aqueous-processable hybrid solar cell applications. The carrier mobility of the aqueous PBTPV is about 5 × 10−4 cm2 V−1 s−1 and the power conversion efficiency of the water-processed PBTPV/CdTe nanocrystal hybrid photovoltaic devices reaches 3.3%.
