In 2016, 90% of polysilicon used worldwide was consumed by the solar industry [ 20 ]. This transformation has led to significant cyclical fluctuations in the market price of polysilicon.
“Polysilicon” is a commonly used term which we will use in this article to refer to any chemical purification process and product going through synthesis and purification of a silicon bearing volatile compound and its decomposition to elementary silicon for the purpose of making semiconductors or solar cells.
PV module followed by cell manufacturing had the highest shares. In general, the calculated impacts are lower than those presented in previous studies, also for polysilicon, due to the update (most frequently reducing the quantity of materials and energy employed) of the inventories of the different stages of PV manufacturing.
Herein, the current and future projected polysilicon demand for the photovoltaic (PV) industry toward broad electrification scenarios with 63.4 TW of PV installed by 2050 is studied. The current polysilicon demand by the PV industry in 2021 is equivalent to the consumption of 2.9–3.3 kt GW −1.
While polysilicon and multisilicon are often used as synonyms, multicrystalline usually refers to crystals larger than one millimetre. Multicrystalline solar cells are the most common type of solar cells in the fast-growing PV market and consume most of the worldwide produced polysilicon.
However, it is the subject of numerous development projects within both incumbent and new producers of polysilicon. FBRs are used in many industrial processes, for instance for gasoline production and coal gasification.
