Solar Cell Consisting of a Single Molecule: Individual Protein Complex Generates Electric Current

• http://www.sciencedaily.com, ScienceDaily
 An team of scientists, led by Joachim Reichert, Johannes Barth, and Alexander Holleitner (Technische Universitaet Muenchen, Clusters of Excellence MAP and NIM), and Itai Carmeli (Tel Aviv University) developed a method to measure photocurrents of a single functionalized photosynthetic protein system. The scientists could demonstrate that such a system can be integrated and selectively addressed in artificial photovoltaic device architectures while retaining their biomolecular functional properties.
 

The proteins represent light-driven, highly efficient single-molecule electron pumps that can act as current generators in nanoscale electric circuits.

The interdisciplinary team publishes the results in Nature Nanotechnology this week.
