Silicon is a semiconductor in group IVA of the periodic table with atomic number 14, an atomic weight of 28.086, and a density of 2.33 Mg/m 3. It melts at 1410 C. The electronic configuration of the ...

A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their ...

The use of n-type and p-type silicon is a foundation concept in the design of transistors. Pure silicon is not conductive. However, it can be made conductive by adding other elements to its ...

However, conventional silicon photonic structures, known as waveguides, struggle to keep sound waves confined. Sound tends to escape into the silicon oxide layer underneath the silicon structures ...

Silicon is the best-known semiconductor material. However, controlled nanostructuring drastically alters the material's properties. Using a specially developed etching apparatus, a team at HZB has ...

A research group led by Chinese manufacturer JinkoSolar has developed a tandem perovskite-silicon cell with a subcell based on TOPCon tech. The group succeeded in reducing voltage losses in the ...
