New solar cells concepts and solar cell efficiency is currently one of the strongest research fields worldwide. Among others, organic solar cells have a great potential and have shown constantly increasing power-conversion efficiencies. In order to ensure a constant improvement in the future, one needs to get a better microscopic insight into the elementary charge transfer processes. Here we will study the influence of vibrational properties of the underlying molecular materials on light absorption and charge transfer. We plan a series of simulations of models of donor-acceptor blends regarding their absorption behavior and electronic properties. We will connect this to key parameters of solar cells and thus get microscopic insight to present efficiency limitations and how to overcome them.
