2019/03/19· Description. Based on silicon and carbon, SiC is used in LEDs and power electronics. SiC has a bandgap of 3.3 eV. Silicon has a bandgap of 1.1 eV. Wide bandgap refers to higher voltage electronic band gaps in devices, which are larger than 1 electronvolt (eV). Today, SiC diodes are used in high-end power supplies for servers and telecom systems
The optical properties of silicon measure at 300K 1. While a wide range of wavelengths is given here, silicon solar cells typical only operate from 400 to 1100 nm. There is a more up to date set of data in Green 2008 2. It is available in tabulated form from pvlighthouse as text and in graphical format. The data on this page is also available

2017/03/08· The findings outlined above describe the evolution of the as-deposited films from silicon carbide-like to silicon dioxide-like films as the amount of C decreases. Regarding the annealed samples up to 700°C, the IR absorption behavior remains similar to the case of their as-deposited counterparts, and it is worth mentioning that changes took place at annealing temperatures beyond 900°C [ 44

In some sensors it is possible to add additional VIS or IR blocking for appliions where the amount of visible light is more than 100 or 1000 times stronger than the UV levels. Silicon Carbide and Vacuum phototubes are a good alternative as they have no visible and IR sensitivity, however they may also face similar problems if the aient environment or light source under test also contains
