Colloidal nanoparticles such as CdSe quantum dots are widely studied for their applications in optoelectronic devices and their blends with conjugated polymers present a promising approach to solar energy conversion. However, solar cells based on nanoparticles exhibit inferior power conversion efficiencies compared to their PCBM‐based counterparts. This presentation will discuss the effects of nanoparticle shape, polymer band gap, and contribution of both the polymer and the nanoparticles to device efficiency and correlate it with exciton dissociation, charge carrier recombination using transient microwave conductivity, an electrodeless technique to monitor the presence of mobile charge carriers. These interfacial studies have led to the best reported certified efficiency of a CdSe:polymer device of 3.2%.
