Quantum mechanics paves the way for more stable organic solar cells

Quantum mechanics can be used to create more stable and more easily produced organic solar cells. These are the findings of new research from the University of Gothenburg.

Organic solar cells have many advantages compared with traditional silicon-based solar cells. They can be manufactured cheaply at a large scale using printing presses, and they are light, malleable and flexible. The problem is that today's organic solar cells are not as stable and effective as silicon-based solar cells. In a new study, a research group has taken on this problem and found a way that can lead to more cost-effective solar cell technology.

"There are excellent opportunities for utilizing quantum efficiencies to change different chemical and material characteristics. In this study, we present a method that makes it possible to increase diffusion of energy in organic materials. This allows us to create organic solar cells with simpler structure," says Karl Börjesson, professor of physical chemistry at the University of Gothenburg and the main author of the study.
