HARVEST - From natural to artificial light-harvesting systems: unveiling fundamental processes towards a bio-inspired materials design

Prin: Progetti Di Ricerca Di Rilevante Interesse Nazionale – Bando 2017

This project employs a combined experimental—theoretical approach to elucidate the molecular mechanisms of light-harvesting (LH) in natural pigment-protein complexes and optimize them for artificial LH systems. High time resolution ultrafast optical spectroscopy will be performed on highly controlled samples of both natural (from plants and mosses) and artificial (organic photovoltaic materials) LH systems. Experiments on natural systems will be compared to computational results, using a quantum mechanical description of the pigments and a classical description of the protein matrix and the environment. For artificial polymer-based materials, ab-initio and density matrix approaches will be used to unveil the nature of excitonic states and strong coupling to vibrations. Based on these microscopic descriptions, a quantitative analysis of LH in both natural and artificial systems will be provided in terms of quantum information theoretical quantities. This will allow us to elucidate the molecular mechanisms and the role played by quantum coherences in LH processes, and their relation to the systems’ structural and electronic properties, paving the way to artificial materials design through bio-inspired strategies.
