Abstract

There is an increased interest in exploiting photophysical phenomena to enhance the performance of photovoltaic technologies, pushing their efficiency toward, and ultimately beyond, the Shockley-Queisser limit for a single-junction solar cell. This presentation will discuss the applicability of molecular chromophores to this endeavor, focusing on two well-known phenomena: (1) photochemical upconversion and (2) singlet fission. Recent discoveries have demonstrated that these ‘scientific curiosities’ exhibit significant promise for solar photoconversion applications. I will outline the mechanisms that underlay these two photon harvesting processes; highlight scientific questions that remain to be answered; and identify strategies for, and obstacles to, their incorporation into realistic photoconversion systems.
