Photonics and Photovoltaics

This research field axis mainly brings together researchers from Light Engineering and Conversion team (i-Lum).


The Nanophotonics can be defined as the field of research that aims at controlling the propagation of light and its interaction with matter at the wavelength scale. These new concepts allow for the achievements of innovative optoelectronic functions, the characteristics and performance of which go far beyond the current state of the art of optoelectronics.


In the field of photovoltaics, research work is focused on the development of innovative materials and processes for high efficiency silicon solar cells, the development of thin-film solar cells, understanding the intrinsic mechanisms limiting conversion efficiency in materials of low purity and finally the contribution of nanotechnologies and nanomaterials for the development of 3rd generation solar cells.
