Biogenic Photovoltaics: A Biogenic Photovoltaic Material (small 26/2018)

Reliable generation and supply of clean energy is critical for de-carbonization of the economy, and solar energy is a leading candidate for achieving this goal. In article number 1800729, Sarvesh Kumar Srivastava, Vikramaditya G. Yadav, and co-workers synthesize a class of biogenic photovoltaics by coating lycopene producing E. coli cells with TiO2 nanoparticles using supramolecular chemistry. When this material is employed as an anode in a dye-sensitized solar cell, it yields an excellent photovoltaic response, laying the foundation for truly “nature-derived” organic optoelectronics.
