Answer:
Silicon is one of the highest quality semiconductors that is ideal for solar cell production. The superior quality of silicon’s electronic, optical, thermal, and environmental properties are best for producing solar cells. Also, the availability and affordability make it more usable for solar panels.
These are the five properties. Hopefully, this helps! :)
Disgusting, depressing, and misery. Tap water is beyond formidable.
