6 FAQs about [Structure of polycrystalline silicon solar cells]
What is polycrystalline silicon?
Polycrystalline silicon, or multicrystalline silicon, also called polysilicon, poly-Si, or mc-Si, is a high purity, polycrystalline form of silicon, used as a raw material by the solar photovoltaic and electronics industry. Polysilicon is produced from metallurgical grade silicon by a chemical purification process, called the Siemens process.
Are polycrystalline silicon based solar cells resonable?
Basic polycrystalline silicon based solar cells with a total area efficiency of app. 5% has been fabricated without the involvement of anti-reflecting coating. This is a resonable result considering that comercial high efficiency solar cells have a con-version efficiency of about 22%, as outlined in chapter 1.
What is a microcrystalline silicon solar cell?
So called “microcrystalline” or “micromorph” silicon solar cell materials consisting of nanocrystallites embedded in an amorphous matrix , , and silicon transfer techniques from wafers , , are therefore excluded from this review.
What is the role of silicon in Polycrystalline cells?
Cells 92 (4) (2008) 418–424, Copyright (2008), with permission from Elsevier. Si played a vital role in the fabrication of polycrystalline cells until 1997. Silicon was needed for many applications such as microelectronic devices and PV devices, and the cost is very important to design PV devices.
What is a single crystal crystalline silicon?
Semiconductor grade (also solar grade) polycrystalline silicon is converted to single-crystal silicon – meaning that the randomly associated crystallites of silicon in polycrystalline silicon are converted to a large single crystal. Single-crystal silicon is used to manufacture most Si-based microelectronic devices.
Why are polycrystalline solar cells less efficient than monocrystalline silicon cells?
Due to these defects, polycrystalline cells absorb less solar energy, produce consequently less electricity and are thus less efficient than monocrystalline silicon (mono-Si) cells. Due to their slightly lower efficiency, poly-Si/ mc-Si cells are conventionally a bit larger, resulting in comparably larger PV modules, too.
