6 FAQs about [Summary of the work of solar silicon wafer screen]
What is a solar wafer?
A solar wafer is a thin slice of a crystalline silicon (semiconductor), which works as a substrate for microeconomic devices for fabricating integrated circuits in photovoltaics (PVs) to manufacture solar cells. This is also called as Silicon wafer.
Can silicon wafers be used to make solar cells?
Once the silicon wafers are fabricated, they can be used to manufacture solar cells. As you learned in Chapter 3, a solar cell is fundamentally a device optimized to absorb light, generate carriers (electrons and holes), and selectively extract them through its terminals in the form of a current flowing through a load.
