Laboratory of Analysis of Materials’ and Molecules’ Photoactivity (LAMP)
The LAMP is a characterization service with three major axis:
- Robotized characterization of solar devices (ex : solar cells)
- Electrochemical and photophysical (transient and steady state) characterization of molecular systems.
- Monitoring of photoreaction or electrolysis.
SERVICES
We offer specialized electrochemical and photophysical characterization in inert atmosphere conditions for:
- Photoactive device mounted on glass substrate:
Photovoltaics, OPV, DSSC, LED, OLED; - Molecules (or reaction) in solution;
- bulk film or powder material.
We also offer custom LED based photo-reactors, suited for studying photo-catalytical reactions or electro-catalytical reactions with continuous monitoring of generated permanent gases (H2, CO, CO2, CH4).
A robotized fabrication service for photoactive devices is planned for 2018, more details to come.
