In order to convert light energy into chemical energy in an environmentally friendly way, bioelectrodes containing a photosynthesis protein complex, the so-called photosystem I, could be useful. So far, however, such electrodes have not been functional in the long term – although the photosystem I is stable in nature. RUB researchers describe why this is the case in the renowned journal Nature Communications.

They demonstrated that irradiation with light produced reactive oxygen species and hydrogen peroxide, which can damage the photosystem I in the long term. The findings could help to develop stable solutions in the future.
