Bulk characteristics of crystalline silicon solar cells. The forbidden band of crystalline silicon falls into an indirect bandgap of E g = 1.12 eV and a direct bandgap of E g = 3 eV .

The workhorse of present PVs is crystalline silicon (c-Si) technology; it covers more than 93% of present production, as processes have been optimized and costs consistently lowered. The aim of this chapter is to present and explain the basic issues relating to the construction and manufacturing of PV cells and modules from c-Si.
Crystalline silicon is a very importance material for solar cells. Unfortunately, due to the high refractive index of silicon, more than 30% of incident light is reflected back from the surface of crystalline silicon. The ARS arrays directly patterned on the silicon substrates [58–62] can effectively suppress the reflection.
Crystalline silicon solar cells are the most widely used solar cells, which have intrinsic limitation on the theoretical conversion efficiency (33.7% based on Shockley and Queisser's analysis) , and the actual conversion efficiency of crystalline silicon solar cells is as low as 20%.
Crystalline silicon is well known as one of the most useful semiconductors for electronic devices. Many theoretical calculations on the electronic structure of crystalline silicon have been done by the band structure calculation or the cluster method.
The poly-crystalline silicon cells are made from the electronics industry residues in the axially cooled ingots form which are then cut into thin wafers. They are optimized for commercial use and have a shorter life span as they are affected by high temperatures. Figure 4.3. Crystalline silicon PV cells: (A) c-Si mono cell, (B) c-Si poly cell.
Thus, protocrystalline and amorphous silicon can be combined in a tandem solar cell where the top layer of thin protocrystalline silicon absorbs short-wavelength light whereas the longer wavelengths are absorbed by the underlying a-Si substrate.
