Energy Use

New materials and designs for solar cells and thin films for energy purposes.

At the Centre for Applied Photonics (CAP), we pursue the development of new materials and designs for solar cells. We also employ our vast knowledge and expertise in the emerging area of thin films.

By investing in solar cells and thin films, we are taking a step forward in terms of rational and efficient energy use. The aim with this activity is to make it possible to obtain concentrating solar cells under different preparation conditions. The ultimate goal is to find the best absorption band spectrum, increase the amount of solar energy absorbed or decrease resistive and recombination losses, and consequently increase these cells’ efficiency.

The RF magnetron sputtering deposition method has been used to obtain CdS/CdTe thin film solar cells. The cells obtained present a post-annealing efficiency potential of 7%. This fabrication process makes it possible to combine several active layers in a clean environment. This way, it is possible to use the solar spectrum more effectively and consequently the produced cell will perform more efficiently.
