Concentration dependent energy levels shifts in donor-acceptor mixtures due to intermolecular electrostatic interaction
Abstract Recent progress in the improvement of organic solar cells lead to a power conversion efficiency to over 16%. One of the key factors for this improvement is a more favorable energy level alignment between donor and acceptor materials, which demonstrates that the properties of interfaces betw...
