Transparent silicon carbide/tunnel SiO2 passivation for …

N‐type microcrystalline silicon carbide (μc‐SiC:H(n)) is a wide bandgap material that is very promising for the use on the front side of crystalline silicon (c‐Si) solar cells. It offers a high optical transparency and a suitable refractive index that reduces parasitic absorption and reflection losses, respectively.

What is a Silicon Wafer? Silicon Valley Microelectronics

What is a Silicon Wafer? Silicon is a gray, brittle, tetravalent, chemical element. It makes up 27.8% of the earth’s crust and next to oxygen, it is the most abundant element in nature. Some of the most common materials that contain silicon are quartz, agate, flint
