5.1. Silicon wafer fabrication The vast majority of silicon solar cells in the market are fabricated on mono- or multicrystalline silicon wafers. The largest fraction of PV modules are fabricated with crystalline solar cells today, having multicrystalline cells been relegated to a few percent of market share, followed by thin film-based cells.
Material processing in solar cell fabrication is based on three major steps: texturing, diffusion, and passivation/anti-reflection film. Wafer surfaces are damaged and contaminated during slicing process. Alkaline and acid wet-chemical processes are employed to etch damaged layers as well as create randomly textured surfaces.
The fabrication of this solar cell design comprises these general steps: a. Surface preparation by cleaning and texturing to minimize light reflection. b. Diffusing an n-type dopant into the p-type wafer to form a pn junction. Back passivation through a BSF formed by Al diffusion.
Hence, the gettering process further purifies the silicon wafer. This gives room for using lower quality (and lower cost) silicon material to fabricate the wafers, knowing that they will be further purified during the solar cell fabrication.
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.
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.
