, 2022 This chapter describes what photosynthetic light harvesting is, why it is needed, and how it works. Light absorption by two types of photosystems drives oxygenic photosynthesis. The light-harvesting capacity and efficiency of these photosystems depend on their structure, pigment composition, and number of pigments per photosystem. The structures of the

Photosynthesis without β-carotene
eLife, 2020 Carotenoids are essential in oxygenic photosynthesis: they stabilize the pigment–protein complexes, are active in harvesting sunlight and in photoprotection. In plants, they are present as carotenes and their oxygenated derivatives, xanthophylls.

Exciton coupling induces vibronic hyperchromism in light-harvesting complexes
New Journal of Physics, 2014 The recently suggested possibility that weak vibronic transitions can be excitonically enhanced in light-harvesting complexes is studied in detail. A vibronic exciton dimer model that includes ground-state vibrations is investigated using the multi ...

Photoinduced electron transfer processes of single-wall carbon nanotube (SWCNT)–based hybrids
Nanophotonics, 2020 In this review, noncovalent functionalization of single-wall carbon nanotubes (SWCNTs) is briefly reviewed. The functional materials summarized here include metalloporphyrin derivatives, biomolecules and conjugated polymers.

Advanced Science, 2020 Multichromophore systems (MCSs) are envisioned as building blocks of molecular optoelectronic devices. While it is important to understand the characteristics of energy transfer in MCSs, the effect of multiple donors on energy transfer has not been ...

Plants, 2021 Leaves have evolved to effectively harvest light, and, in parallel, to balance photosynthetic CO2 assimilation with water losses. At times, leaves must operate under light limiting conditions while at other instances (temporally distant or even within ...

Light-Harvesting Complex: Rings of light [PDF]
Current Biology, 1995 The atomic structure of the bacterial light-harvesting complex helps to explain how the energy of sunlight is efficiently absorbed and transferred between bacteriochlorophyll molecules towards the reaction centre.

Photonic crystal based photoelectrochemical cell for solar fuels
Nano Select, 2021 The solar fuel production efficiency of photoelectrochemical cells based on TiO2 is primarily limited by the low optical absorption coefficient and concomitant long penetration depth of visible light compared with the minority charge carrier diffusion ...

Dynamics of photosynthetic complexes in the thylakoid membranes from higher plants [PDF]
, 2011 PhDPhotosynthetic machinery in higher plants is localised in the thylakoids enclosed in a chloroplast. To optimise and regulate the photosynthetic efficiency under different, rapidly changeable environmental conditions the dynamics of the thylakoid
