Project Member(s): Reimers, J.

Funding or Partner Organisation: Australian Research Council (ARC Discovery Projects)

Start year: 2015

Summary: The nature and role of the lowest-energy excited states in most natural photosynthetic reaction centres and light-harvesting complexes will be determined. The lowest-energy states of bacterial reaction centres are critical to function and are used as a paradigm in artificial organic solar-energy capture, but for most photosystems their nature remains unknown and a critical question that we shall answer is to why they do not actually prevent function. Both the outcomes obtained and techniques developed will be directly relevant to solar-energy device design. We will apply 5 existing, complimentary, and purposely built spectrometers as well as quantum electronic and nuclear simulation techniques to identify and characterise 3 key systems.
