Project description

The research focuses on optimizing the optical properties of key components in concentrating solar collectors used for production of thermal energy. The components in question are mainly the receiver and the cover glass. The receiver in a solar collector has a coating that makes it optically selective, which means that it has high absorptance of sunlight and low emission of thermal radiation.

Erik Zäll is working on developing a new type of electroplated selective coating for Absolicon's receiver tubes. The cover glass in a solar collector is treated with an anti-reflective coating to maximize the transmittance of sunlight. In this area, he leads a project where Umeå university, Absolicon and RISE collaborate to develop a new anti-reflective coating for the cover glass.

The glass project is financed by grants from Vinnova that was received through a joint application.
