A multi-pathway model for photosynthetic reaction center.
Charge separation occurs in a pair of tightly coupled chlorophylls at the heart of photosynthetic reaction centers of both plants and bacteria. Recently it has been shown that quantum coherence can, in principle, enhance the efficiency of a solar cell, working like a quantum heat engine. Here, we propose a biological quantum heat engine (BQHE) motivated by Photosystem II reaction center (PSII R...
متن کاملElectron transfer in the photosynthetic reaction center.
Photosynthesis occurs via electron transfer between pigment molecules or prosthetic groups embedded in a thylakoid membrane protein complex. These pigments form the “conductive pathway” for electron flow and the surrounding protein serves as a“shaping insulator”. Electron transfer through the protein proceeds via quantum tunneling into succesively lower potential wells represented by the pigmen...

متن کاملPhotosynthetic reaction center as a quantum heat engine.
Two seemingly unrelated effects attributed to quantum coherence have been reported recently in natural and artificial light-harvesting systems. First, an enhanced solar cell efficiency was predicted and second, population oscillations were measured in photosynthetic antennae excited by sequences of coherent ultrashort laser pulses. Because both systems operate as quantum heat engines (QHEs) tha...
متن کاملPrimary charge-recombination in an artificial photosynthetic reaction center.
Photoinduced primary charge-separation and charge-recombination are characterized by a combination of time-resolved optical and EPR measurements of a fullerene-porphyrin-linked triad that undergoes fast, stepwise charge-separation processes. The electronic coupling for the energy-wasting charge recombination is evaluated from the singlet-triplet electronic energy gap in the short-lived, primary...
