Organic Photovoltaics: Current and Future(?) Technologies
 

Dale Heggie

Organic photovoltaics have the capability to become a major contributor
of renewable energy in the future.   There is currently much motivation in this research area because of the potential manufacturing ease and  low consumer costs.  The conversion efficiency obtained by these types  of devices today has not met the 10% target; with the limiting factors  being the diffusion and dissociation of excitons and the mobility of  charge carriers.  Techniques to combat this low efficiency, such as  single layer, heterojunction, dispersed heterojunction, dye-sensitized,  and nanotube/C60 devices will be discussed. The research lab and experimental techniques will be introduced, as this will allow novel designs with the hope of improved efficiency.
