A central challenge in photovoltaics is to develop and implement approaches that allow photovoltaics to reach their thermodynamic efficiency limits. Tandem solar cells allow high efficiency; but as the number of solar cells in the tandem stack increases, they require increasing numbers of ideal, compatible materials and the incremental efficiency gains become smaller. An alternative approach is to develop solar cell structures based on previously unutilized physical mechanisms. The central goal of the University of Delaware's project is to develop the physical understanding, design rules, materials, and device approaches to implement advanced concept photovoltaics, focusing particularly on multiple quasi-Fermi level or intermediate-band approaches.
