Scientists achieve first step in converting solar energy using 'artificial leaf'

Abstract:
An international team of researchers has achieved the first step in converting solar energy using an 'artificial leaf'.

The researchers have modified chlorophyll from an alga so that it resembles the extremely efficient light antennae of bacteria.

The team was then able to determine the structure of these light antennae. This is the first step to converting sunlight into energy using an artificial leaf.

German colleagues from the University of Wurzburg in Huub de Groot's team modified chlorophylls from the alga Spirulina, such that they resembled the pigments of bacteria. de Groot's Leiden group then studied the structure of these semi-synthetic light antennae.
