At materials molecular level, photoelectric/photovoltaic conversion corresponds to a photo induced electron transfer from a molecular electron rich donor entity to an electron deficient acceptor entity, and the process is also called photo induced exciton dissociation [1-3]. In addition to solar energy such as solar cell applications, photoelectric/photovoltaic materials can also be used in photo-detector applications such as in photo-electric signal transducers in optical communication or optical imaging systems. This presentation will provide a brief overview on the mechanisms, brief history, current status, and future prospective of polymer or ‘soft materials’ based photoelectric conversion materials, with a focus on block copolymer nanostructure approaches to address the loss issues in current polymer solar cells. For example, Figure 1 exhibits a general scheme of a conjugated block copolymer tertiary nanostructure approach conducted at presenter’s lab [6-8]. Some preliminary results from such studies will be presented.
