Organic solar cells have a photoactive layer that is made from polymers and small molecules. The cells are very thin, can be flexible, and are easy to make. However, the efficiency of these cells is still much below that of conventional silicon-based ones. Applied physicists from the University of Groningen have now fabricated an organic solar cell with an efficiency of over 17 percent, which is in the top range for this type of material.

In organic solar cells, carbon-based polymers convert light into charges that are passed to an acceptor. Scientists from the University of Groningen have now calculated how this happens by combining molecular dynamics simulations with quantum calculations and have provided theoretical insights to interpret experimental data.

Our society must end its addiction to oil and gas. This means that we need a new source of hydrocarbons, the carbon compounds from which fuels and many fossil-based materials are made.
