Silicon Wafers: Production, Properties and Application

Silicon''s ability to absorb sunlight and its semiconductor nature makes it an ideal material for solar cells. When sunlight hits the silicon wafer in a solar cell, it excites the electrons, causing them to move and create an electric current. There are two main types of

Silicon Solar Cell Parameters

N-type silicon has a higher surface quality than p-type silicon so it is placed at the front of the cell where most of the light is absorbed. Thus the top of the cell is the negative terminal and the rear of the cell is the positive terminal.

Solar Cell Efficiency: N-type v. P-type

The difference between p-type and n-type crystalline solar cells. The raw material that precedes the the pulling and cutting of silicon wafers is the same for both p and n-type cells. This raw silicon feedstock is "grown" into ingots (Czochralski process) or cast as bricks and then thinly sliced. These wafers form the basis of a solar cell.

After nanowire formation, type test was necessary for p-type emitter surface on n-type silicon wafer by hot probe test method. In profile 1, 2, and 3, 5 junctions were there, but implied V oc was very small and sheet resistance was 300-600Ω/ which were not adequate for a highly efficient solar cell.

Wafer (electronics)

In electronics, a wafer (also called a slice or substrate) [1] is a thin slice of semiconductor, such as a crystalline silicon (c-Si, silicium), used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells.. The wafer serves as the substrate for microelectronic devices built in and upon the wafer. It undergoes many microfabrication processes, such as …
