Abstract

Read online

Photosynthetic proteins are used to harvest solar energy in bio-photovoltaics, but are typically not investigated for charge storage. Here the authors report prolonged charge storage in multilayers of photoproteins as well as a proof-of-principle biophotonic power cell with purple bacterial photoproteins.
