Organic/inorganic semiconductor blends offer several potential advantages over all-organic systems in photovoltaic applications. However, all-organic photovoltiacs at present exhibit far higher efficiencies in solid state devices. We study charge transfer and recombination at the polymer/quantum dot interface in a series of conjugated polymers with a wide range of inorganic acceptors. In addition to identifying promising new materials combinations, we also highlight the role of semiconductor surface states on device performance, and explore the possibility that higher dielectric constant inorganic acceptors may offer better performance than organic acceptors�if surface chemistry and film morphology can be optimized.
