Light-harvesting process

To reveal the light-harvesting process, synthetic studies on cyclic porphyrin oligomers, designed based on the information of the protein structure, are considered. Nature adopted the cyclic alignment of chlorophyll. Is the closed cyclic... 

Carotenoids complement chlorophylls in the light-harvesting process. 

It is important to emphasize that this structure based approach on studying excitation transfer dynamics contains no arbitrary parameters. Geometrical information about the chlorophyll network, combined with the application of basic physical principles of excitation transfer determines the values of all dynamical quantities. Thus, a comparison with observation essentially provides a test for our understanding of the physics of the light harvesting process. 

Robustness Parameter insensitivity. External perturbations, such as the effects of thermal disorder, or modifications to network geometry have little effect on the overall efficiency of the light harvesting process.
