Stanford engineers invent transparent coating that cools solar cells to boost efficiency PDF Imprimer Envoyer
Technologies et procédés

The hotter solar cells become, the less efficient they are at converting sunlight to electricity, a problem that has long vexed the solar industry. Now, Stanford engineers have developed a transparent overlay that increases efficiency by cooling the cells even in full sunlight.

NAL develops new sputtered Absorber Coating PDF Imprimer Envoyer
Technologies et procédés

The Surface Engineering Division of the Bengaluru-based Indian National Aerospace Laboratories (NAL) has developed a new sputtered absorber coating, which could be applied to 6" stainless steel tubes of Concentrating Solar Power (CSP) plants once the technology has passed the laboratory stage. A Magnetron sputtering process is used to cover the surface with the TiAlN/TiAlON/Si3N4 tandem coating.

Rotating receiver heats up ceramic beads PDF Imprimer Envoyer
Matériaux

Until now, tube receivers have been used in solar tower power plants to absorb the concentrated solar rays and convert them into heat. The German Aerospace Centre (DLR) is now pursuing a new approach. In a rotating receiver, ceramic particles are evenly heated up to 1,000 degrees Celsius. The advantage of this is that the beads also act as a storage medium. The centrifugal receiver at the Jülich solar tower is scheduled to enter operation from mid-2015.
