Thanks to its high efficiency-solar cells, CESI gave its contribution to a prestigious project that has recently been explained on the scientific magazine Nature.
In particular, l'Ecole polytechnique fédérale de Lausanne (EPFL) was able to achieve a record solar hydrogen production with concentrated sunlight,keeping a high solar-to-fuel efficiency. In fact, efficient solar hydrogen production requires rare materials, the catalyst and solar cells, in order to collect energy and then convert it.
Using CESI’ high efficiency solar cells, scientists at EPFL came up with the idea of concentrating solar irradiation to produce a larger amount of hydrogen over a given area at a lower cost. They developed a system that can turn solar power into hydrogen. The results from the lab-scale demonstrations are very promising, opening a new pathway towards the large scale deployment of photo-electrochemical hydrogen production.
