In a solar redox flow battery sunlight transforms the active molecules from the discharged to the charged state by the help of a photoelectrode made e.g. from silicon. Thereby the battery is charged directly and by itself from sunlight.

In an hour and a half the sun delivers to the Earth roughly the same amount of energy that humankind consumes in 1 year, so solar energy capture and storage are of vital importance for the future renewable energy system. During her Ph.D., Kristina Korning Wedege has developed and tested photoelectrochemical flow batteries made from low-cost, environmentally friendly, and organic chemicals. The batteries can, on one hand, be used for storage of surplus power from the grid, and on the other for direct conversion of solar energy into storable electricity.

The Ph.D. degree was completed at the Department of Engineering - Electrochemical Energy Conversion and Batteries, Science & Technology, Aarhus University.

This résumé was prepared by the Ph.D. student.
