The growing demand for sustainable energy led to the idea of using natural photosynthetic enzymes in semi-artificial devices. However, researchers in this field soon faced drastically increased instability of such enzymes when used under artificial conditions, preventing their industrial application. Vincent Friebe and his collaborators succeeded in significantly extending the lifetime of such biohybrid photocathodes by maintaining electron transfer during operation. This extended the total lifetime to more than one month. Learn more about this in their new publication in Angewandte Chemie.
