This information was used to enhance the quantum dot material quality by developing more effective post-deposition treatments defect annealing and hydrogen passivation for the absorber layers. Bringing together experts from the fields of material science, chemistry, surface passivation and physics, the team set out to better harness the solar spectrum by inventing both new materials capable of yielding high-power conversion efficiency solar cells and novel panchromatic semiconductors based on environmentally friendly compounds and processes.
Galvanised steel parts electroplated with a corrosion-protecting zinc Zn coating often undergo a final post-fabrication process called passivation. The Commission confirms that oiled CRS does not fall under the scope of the investigation, in case it is merely oiled and not chemically passivated and oiled at the same time. The surface of the product is further treated with chemical passivation to protect the surface against humidity and to reduce the risk of formation of corrosion products during storage and transportation.
The alkaline properties and the anodic passivation properties of the borate ion enhance the anticorrosion performance.
