Photovoltaic concepts inspired by coherence effects in photosynthetic systems

Brédas, Jean-Luc, Sargent, Edward H., Scholes, Gregory D.·2017·Nature Materials

Abstract

The past decade has seen rapid advances in our understanding of how coherent and vibronic phenomena in biological photosynthetic systems aid in the efficient transport of energy from light-harvesting antennas to photosynthetic reaction centres. Such coherence effects suggest strategies to increase transport lengths even in the presence of structural disorder. Here we explore how these principles could be exploited in making improved solar cells. We investigate in depth the case of organic materials, systems in which energy and charge transport stand to be improved by overcoming challenges that arise from the effects of static and dynamic disorder - structural and energetic - and from inherently strong electron-vibration couplings. We discuss how solar-cell device architectures can evolve to use coherence-exploiting materials, and we speculate as to the prospects for a coherent energy conversion system. We conclude with a survey of the impacts of coherence and bioinspiration on diverse solar-energy harvesting solutions, including artificial photosynthetic systems.

  • Transport on time scales of about 100 femtoseconds is impossible to explain within classical Marcus hopping models, and coherent transfer must explicitly be included.

    “Transport on such time scales is impossible to explain within classical Marcus 'hopping' models and the coherent transfer must explicitly be included [81,82].”

  • A number of experiments have observed that a substantial fraction of free charges are generated within just 100 femtoseconds of the exciton reaching an interface, just as femtosecond coherences and dynamics have been observed during photosynthetic exciton transport.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
