light energy. Thus, if exposed to light, there is a continuous electricity flow within the closed system.

Efficiency may be increased

In order to convert solar into electric energy, there must be a potential difference between the two electrodes. The Bochum researchers have established this difference by deploying redox hydrogels with different potentials. The potential difference determines the bio photovoltaic cell's voltage and, consequently, its efficiency. Currently, the bio-based solar cell boasts an efficiency of several nanowatts per square centimetre. "The system may be considered a blue print for the development of semi-artificial and natural cell systems in which photosynthesis is used for the light-driven production of secondary energy carriers such as hydrogen," says Prof Rgner.
