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.
How are solar cells made?

What is a solar cell fabrication process?
A solar cell fabrication process uses several high-temperature steps including a phosphorus diffusion process and a metal contact firing. The silicon wafer is p-type doped to 1 · 10 15 cm −3. The required surface doping and depth for the diffused part of the pn junction are 1 · 10 19 cm −3 and 200 nm, respectively.
How pn junction is formed in silicon solar cells?
Constant-source and constant-dose diffusion are the most common in silicon solar cell fabrication. Typical processes to form the pn junction in silicon solar cells comprise two steps: A pre-deposition process with a constant source, such as process A defined previously, to introduce the desired dose of dopant impurities in the wafer surface.
How do you make a wafer for a solar cell?
Wafer preparation Once the monocrystalline or multicrystalline ingots are fabricated, they must be shaped and sawed into wafers for subsequent solar cell fabrication. This process implies a material loss. First, the head and tail of the ingot are discarded, and the ingot is given a square shape by cutting off the edges.
