Understanding the factors affecting energy loss in organic photovoltaics (OPVs) is imperative to achieve further improvements in their efficiency and to establish design rules for the development of new materials. By studying several planar and bulk heterojunction solar cells, an international team of researchers (USA – Princeton University, Saudi Arabia) has demonstrated that the non-radiative energy loss component quadratically increases with increasing Gaussian CT-state disorder. They showed that by defining the total energy loss in terms of the peak of the CT-state distribution the effect of disorder on OPV performance can be unambiguously identified, offering a universal metric for quantifying energy loss across various devices…read more.
