Investigating limitations of biohybrid photoelectrode using synchronized spectroelectrochemistry

The challenge in optimizing biohybrid photoelectrodes lies in identifying kinetic bottleneck and energy loss of photoinduced electron transfer. In this issue of Joule, Friebe's group describes amethod for synchronized spectroscopic and electrochemical measurements of biophotoelectrode in operando, which indicates the electron transfer bottleneck steps and the energy loss processes.
