AI Customer ServiceSince the inception of the solar industry in the 1960s, it has been predicted that thin-film solar cells will eventually displace solar cells based on silicon wafers.
The forecasted eclipse of silicon wafer-based solar cells has not yet occurred, as presently about 90% or more of commercial solar cell products are still bulk silicon devices made from silicon cast ingots, pulled single-crystal boules, or ribbon/sheet.
Schematic process flow for an industrial crystalline silicon solar cell line. 1. The entrance interface is the wafer in a stack. As a first step the wafers are typically inspected for microcracks using infrared transmission.
Using polycrystalline silicon (p-Si) solar cells as an example, highly pure p-Si ingots are afterward sliced into thin slices called wafers which form the base for the PVs cells. Silicon is a semiconductor and unlike conductors such as metals, it generally does not conduct electricity. However, under certain conditions, it can be made conductive.
A typical silicon PV cell is a thin wafer, usually square or rectangular wafers with dimensions 10cm × 10cm × 0.3mm, consisting of a very thin layer of phosphorous-doped (N-type) silicon on top of a thicker layer of boron-doped (p-type) silicon. You might find these chapters and articles relevant to this topic.
At this point, it is argued, further progress in photovoltaics will rely on emerging thin-film solar cell technologies based on amorphous materials, compound semiconductors, or perhaps even organic polymer, nanomaterials, or other types of solar cells with no current analogues.
