Topic description
La photosynthèse est un processus thermodynamique par lequel une réaction chimique défavorable est convertie en une réaction favorable lors de la récolte de l'énergie lumineuse. Au cours de milliards d'années, la nature a développé des mécanismes chimiques efficaces permettant de récolter l'énergie lumineuse et de la coupler à des réactions chimiques. Pourtant, sous un faible éclairage, le rendement de la photosynthèse diminue considérablement, ce qui se traduit par une faible efficacité et, bien sûr, par un rendement nul dans l'obscurité totale, comme le prévoit la thermodynamique d'équilibre. Un défi expérimental majeur consiste à réorganiser des systèmes biomimétiques capables de récolter efficacement l'énergie lumineuse de manière modulaire, puis de la coupler à des réactions électrochimiques. Nous prévoyons de concevoir des solutions pour augmenter le rendement de la photosynthèse dans diverses conditions expérimentales en utilisant des particules plasmoniques dans des systèmes souples. Notre projet conduira à la construction ascendante de systèmes biomimétiques pour la conversion de l'énergie photonique en énergie électrochimique.

Photosynthesis is a thermodynamically-driven process by which an unfavorable chemical reaction is converted into a favorable reaction upon light-energy harvesting. Nature has evolved over billions of years efficient chemical machineries allowing for the harvesting of light energy and its coupling into chemical reactions. Yet, under low illumination, the yield of photosynthesis drops significantly resulting in low efficiency and of course to a zero yield in full dark conditions as expected from equilibrium thermodynamics. Being able to re-engineer biomimetic systems capable to harvest light energy efficiently in a modular way, to further couple it to electrochemical reactions is a major experimental challenge. We plan to engineer solutions to increase the yield of photosynthesis under various experimental conditions using plasmonic particles in soft systems. Our project will lead to the bottom-up construction of biomimetic systems for the conversion of photon energy into electrochemical energy.
