Our research department focuses on developing luminescent coatings that are transforming windows into the first electricity- and data generating building appliances, by utilizing the entire glass surface to harness the sun’s power and convert it into clean energy. These windows will be working on the principle of a luminescent solar concentrator (LSC), absorbing the sunlight that is normally reflected by a standard window and re-directing the light towards the edges where integrated PV cells convert it into electricity.
In order to produce such luminescent coatings, two deposition techniques are considered and developed, namely magnetron sputtering and phosphor-embedded (luminescent particles) wet-coatings. At PHYSEE we use stable inorganic luminescent materials that are environmentally friendly (non-toxic). All coatings have broad absorption (from UV over visible to near NIR) as well as sharp emission in the near infrared region, allowing for almost no self-absorption.
