Applications for the Solar Industry

Thin film measurement of anti-reflection coatings on solar cells
The modern diode array technology provides a fast and effective in-line measure of the reflectance and the color of the anti-reflection coating on solar cells. With this information our software is able to calculate the layer thickness of the coating.

This application was built in a joint venture with Vitronic and has won the CellAward 2009.

Spectral sunlight distribution
The development and optimization of new absorber layers for the solar industry requires detailed knowledge of the solar irradiance. As a standard, mainly the characteristic solar irradiance was used.

However, depending on time, location and interaction with the environmental conditions, the actual irradiance is influenced.

Sun light simulators
Efficient manufacturing processes and uniform quality of solar cells and modules rely on a series of quality control measurements. In order to estimate the cells' or modules' efficiency, tests with solar simulators are performed and a classification is done.
The quality monitoring of the testing equipment, in this case the solar simulators, is necessary to get consistent information.

Quality control of solar glass
The fast and precise tec5 MultiSpec spectrometer systems enable an in-line measurement of solar glass in transmittance and reflectance.
Furthermore, tec5 provides established optical measurement setups for measuring huge, structured glass panes.
