FAQS about What is the upgraded version of solar monocrystalline silicon

Is upgraded metallurgical grade silicon a viable alternative to standard polysilicon?

Upgraded metallurgical grade silicon (UMG Si) has already demonstrated to be a viable alternative to standard polysilicon in terms of cost and quality. This study presents the life cycle assessment (LCA) of UMG obtained by the FerroSolar process.

What is upgraded metallurgical grade silicon?

Upgraded metallurgical grade (UMG) silicon is an alternative method of producing solar grade silicon by means of directional solidification. This process exploits the relatively low segregation coefficients of metals to remove impurities and purify the remaining silicon.

What is solar grade silicon (Sog-Si)?

Solar grade silicon (SoG-Si) is a key material for the development of crystalline silicon photovoltaics (PV), which is expected to reach the tera-watt level in the next years and around 50TW in 2050.

Why are crystalline silicon based solar cells dominating the global solar PV market?

Currently, the crystalline silicon (c-Si)-based solar cells are still dominating the global solar PV market because of their abundance, stability, and non-toxicity. 1, 2 However, the conversion efficiency of PV cells is constrained by the spectral mismatch losses, non-radiative recombination and strong thermalisation of charge carriers.

Is silicon a monocrystalline or multicrystalline material?

It is also common in literature to find studies in which the type of silicon used is a mixture of both mono and multicrystalline materials. Moreover, different systems boundaries are defined, and various LCA assessment methods are used, leading to different results.

What is solar grade silicon used for?

Solar grade silicon used by industry as silicon source for crystalline silicon PV devices manufacturing at the present time is produced mainly by a closed-loop Siemens process, in which trichlorosilane Siemens CVD deposition technology is combined with hydrochlorination of silicon tetrachloride for recovery of vent gases.
