For photovoltaic applications, the refractive index, and thickness are chosen in order to minimize reflection for a wavelength of 0.6 µm. This wavelength is chosen since it is close to the peak power of the solar spectrum.
In order to determine the optimal refractive index, we developed a method which encompasses a combined analysis of the electrical and optical properties of SiN layers deposited on multicrystalline silicon solar cells.
The cover glass of the solar panels produced has been produced with anti-reflective coating in recent years. Commercially available Pilkington solar cover glass is coated with the sol-gel method and provides 1–6% more light transmittance. Optitune achieved 3% more light transmittance with single-layer sol-gel coating.
Enter an integer between 1 and 7. This library contains the wavelength-dependent refractive index of materials used in photovoltaic solar cells and modules. It is limited to data published in the scientific literature (except for a couple of materials for which we have no published data). is the wavelength. A material's absorption coefficient
Do not expect that the refractive index provided here represents all manifestations of a material. There could also have been significant experimental error in the associated measurements. The PV Lighthouse website is a free online resource for photovoltaic scientists and engineers.
However, no solid material has a refractive index this low. Magnesium fluoride (MgF 2) is the closest viable material with a refractive index of 1.32 and has been widely used as a single-layer AR coating in research settings as a result , .
