Laboratory of Excellence:LabEx SOLSTICE

[email protected], Univerist de Perpignan, Universit de Montpellier

Our laboratory as been granted a Laboratory of Excellence (LabEx inScience for Energy Conversion) by the Ministry of Higher Educationand of Research of France.

The activities are coordinated by CNRS in partnership with MinesAlbi-Carmaux, Montpellier and Perpignan Univ. This designation isgiven for ten (10) years to only few top laboratories in France.

The missions: to increase scientific excellence and originality, to transfer

knowledge and to increase the international impact of Frenchresearch

to guarantee teaching excellence and have a prominent role in thedevelopment of master and doctorate degrees.

Funding: 5 M up to 2019
