Platinum dimer systems are of great interest because they have physical characteristics reminiscent of chromophores thus giving insight on how to improve solar energy harvesting technology. We are currently concerned with the photoexcitation character of a series of platinum dimer systems as well as the physics of electron transfer between the different excited states. In studying these processes in the platinum dimer structures, more computationally reasonable systems, we will be able to develop and refine models. These models will then be used to better understand the photophysical processes occurring in larger chemical systems relying on photosynthesis. From these newly developed methods we will ideally be able to develop optimal systems for increased solar energy harvesting efficiency, which can be implemented in the next generation of solar cells.
