ABSTRACT
While bulk heterojunction photovoltaic (PV) cells made from conjugated polymers and titania have not yet matched the efficiencies observed in other types of organic photovoltaic cells, they do possess several advantages over other organic photovoltaic cells and have the potential to achieve high efficiency if a few key loss mechanisms can be overcome. In this chapter, we describe the work that has been done to fabricate polymer-titania cells and to characterize their performance. In addition, we highlight some of the physical mechanisms responsible for the generation of open circuit voltage (V OC) and the production of photo-current in these cells. We conclude with an outlook for the future of polymer-titania photovoltaic cells and describe the improvements that will be required to achieve high efficiency.
