Abstract
Photosystem I (PSI) is a key element in Nature's photosynthesis and an attractive building block for bio‐inspired solar energy conversion systems. In article number 1600393, Ryan C. Chiechi, Andreas Herrmann, and co‐workers describe how phage display enables the selection of small peptides that allow almost perfect orientation of PSI on semiconductor electrodes in solid state bio‐photovoltaic devices.
