Researchers from Dutch research institutes of the FOM and Philips will have a combined anti-reflection coating developed solar cells significantly effective lwa nter. The layer consists of silicon nanoparticles.
The anti-reflection coating was developed by employees of Amolf, a part of the FOM-institute, and Philips Research. With a coating of silicon nanoparticles would be solar cells of silicon is less sunlight to reflect. According to the researchers, takes the reflection off of 40 to 1 percent. Due to the decrease in reflection, there is more sunlight for conversion into electricity in the photovoltaic cells.
Thanks to the coating, sunlight is scattered, where 99 percent of the light in the silicon, is reflected. The verstrooiingseffect was achieved by the dimensions of the silicon nanoparticles to tune the wavelength of the incident light. That light resonates in the cavities in the nanoparticles, and then in the lower layer is led, in this case, the siliciumsubstraat of the solar cells.
The researchers developed a simple and cheap method for the nanocoating structure and the silicon. The application is however not limited to coatings for solar panels, but also lenses, the display can be treated.
