Impact of molecular quadrupole moments on the energy levels at organic heterojunctions

Impact of molecular quadrupole moments on the energy levels at organic heterojunctions

The performance of organic semiconductor devices depends heavily on molecular parameters. Here, Schwarze et al. point out that the molecular quadrupole moment largely influences device energy levels and show how quadrupole moments can reduce the energy barrier for charge generation in solar cells.
