Voltage losses limit the performance of organic solar cells, yet their origins are not fully understood. Now, a theoretical model encompassing electronic state hybridization and thermal population vibrational states explains reduced non-radiative voltage in efficient non-fullerene acceptor systems.

Fuel cells, providing an advanced alternative energy source, are devices that can convert chemical into electrical energy. Modeling of a fuel cell provides improvements to the design cells as well cheaper, better and more efficient cells. Three basic voltage losses occur in cell: activation polarization, ohmic polarization concentration polarization. In this study, simulation PEM (proton exchan...

Heterocyclic aromatic hydrocarbons are, together with their un-substituted analogues, widely distributed throughout all environmental compartments. While fate and effects of homocyclic PAHs are well-understood, there are still data gaps concerning the ecotoxicology of heterocyclic PAHs: Only few publications are available investigating these substances using in vitro bioassays. Here, we present...
