Owing to the diminishing of fossil energy sources, the development of renewable energy technologies has attracted great attentions all around the world. Photovoltaic technologies, which can directly convert solar radiation into electricity are promising and practical approaches to utilize solar energy. Among all kinds of photovoltaic technologies, polymer solar cells (PSCs), which are based on the solution-processed physical blend of a p-type semiconducting conjugated polymer (serving as an electron donor) and a n-type fullerene derivative (serving as an electron acceptor) with a bulk-heterojunction (BHJ) structure, have received growing attention due to their immense advantages such as low-cost, light-weight and flexibility. This chapter highlights interface engineering of PSCs with both conventional and inverted configurations by utilization of several representative classes of interfacial materials.
