The efficiency of light harvesting materials is largely determined by the rate at which excitons and charge carriers non-radiatively recombine. There are also several interesting new processes like fission that are governed by complex relaxation dynamics. We will discuss our method for treating excited state relaxation with single electron detail, and the application of this method to light harvesting in Tetracene and organometallic perovskites. The role of relaxation and dephasing in the efficiency of these materials will be related back to the vibronic structure of these materials. The importance of local molecular structure in relaxation dynamics will also be discussed.
