As already explained in Section 8.4.2, c-Si solar cells have to be fabricated from wafers of multi-crystalline or mono-crystalline silicon. In the following sections, the technological processes from preparing pure silicon, to silicon wafer fabrication, to cell design and fabrication, and finally to PV module design and fabrication will be discussed.
Silicon-based solar cells (and consequently modules) still dominate the PV market (more than 85%) compared to other commercially available thin film and third-generation photovoltaics. Apart from the obvious reasons of well-established silicon manufacturing ...
The production of a typical silicon solar cell (Fig. 2) starts with the carbothermic reduction of silicates in an electric arc furnace this process large amounts of electrical energy break the silicon–oxygen bond in SiO 2 via an endothermic reaction with carbon. Molten Si-metal with entrained impurities is withdrawn from the bottom of the …
The thin films used in crystalline silicon solar cells can play various roles in some of these failure mechanisms. ... At the end of the process, the cell parameters are measured (under standard testing conditions), and ... the thin film modules require little or no silicon for their production and the overall production cost is lower compared ...
Moreover, the manufacturing process of monocrystalline cells produces more silicon waste than the manufacturing of other cells. The manufacturing process of monocrystalline solar cells As said in the previous section, the manufacturing process of monocrystalline solar cells is very lengthy and involves a multitude of steps.
The manufacturing processes of the different photovoltaic technologies are presented in this chapter: Crystalline silicon solar cells (both mono- and multi-crystalline), including silicon purification and crystallization processes; thin film solar cells (amorphous silicon, cadmium telluride, chalcopyrites and kesterites); III-V solar cells, …

5.1.1 Production of Silicon Ingots. Crystalline solar cells used for large-scale terrestrial applications consist almost exclusively of silicon as base material. There are good reasons for this: Silicon is the second most abundant element of our Earth''s crust after oxygen. Weighted by atomic per cent, the earth''s crust contains Footnote 1:
Approximately 95% of the total market share of solar cells comes from crystalline silicon materials . The reasons for silicon''s popularity within the PV market are that silicon is available and abundant, and thus relatively cheap. ... The final step in the solar cell production process involves the removal of any conductive layer from the ...
Surface texturing is one of the key steps in the manufacturing process of mono-crystalline silicon solar cells. The mainstream texturing process applied currently is based on alkaline texturing that produces upright pyramids (UPs)-structured surface, while the inverted pyramids (IPs) structure has also received growing interest due to the lower …
