Offer Description

In view of the inevitable climate change, the production of energy from sustainable and renewable resources is a major challenge of the coming decades. A significant amount of energy is received by the planet via solar radiation, which constitutes an almost infinite natural resource. This radiation can be converted into electricity using photovoltaic devices. Currently, the majority of devices based on dye-sensitized solar cells (DSSCs) or organic photovoltaics mainly capture light in the visible range, while a non-negligible proportion of radiation is found in the near-infrared (NIR). This program is part of the breakthrough field of colorless, transparent photovoltaic cells. Efficient photovoltaic technology in the NIR would enable the development of colorless, transparent solar panels that could be integrated into the glazing of buildings, vehicles, greenhouses and autonomous portable devices [1]. For this application, DSSCs are among the most promising devices, as they are simple to implement while offering competitive electricity production over the long term [2]. In this context, the aim is to develop NIR-selective photosensitizers, which is precisely the subject of the present PhD offer.

The TRANSITION project, funded by the Pays de la Loire region, Nantes Metropole and the CNRS, capitalizes our group's expertise and recent results in the fields of NIR dyes and colorless DSSCs [3]. More concretely, it aims to design heterocyclic organic dyes that absorb intensely and specifically in the NIR region, for the development of transparent solar cells. The research is interdisciplinary and particularly challenging: the postdoctoral candidate will develop the synthesis and purification of innovative NIR organic dyes, unravel their photophysical and electrochemical properties, and integrate them in a new generation of transparent solar cells developed in our group at CEISAM, and in collaboration with the team of Dr. F. Sauvage in Amiens.
