The use of antimony in photovoltaics is expected to surpass its flame-retardant usage to become the major downstream use for the metal and will change the supply-demand balance in the antimony industry, a senior industry
One of antimony''s primary uses (accounting for about 50% of consumption) is in the form of antimony trioxide in flame retardants for plastics, textiles and other materials. But the use of antimony as a clarifying agent in
sodium borate and antimony trioxide have also been used as flame retardant additives [–19]. Among them anti16 - mony trioxide has colourless, cubic phase and white colour. Moreover,
With a year''s worth of sunlight providing almost two hundred times the energy of the world''s entire known supply of fossil fuels, solar power is suitably positioned as a strong contender for utility
The rapidly expanding demand for photovoltaics (PVs) requires stable, quick, and easy to manufacture solar cells based on socioeconomically and ecologically viable earth-abundant resources. Sb2S3 has been a potential candidate for
One of antimony’s primary uses (accounting for about 50% of consumption) is in the form of antimony trioxide in flame retardants for plastics, textiles and other materials. But the use of antimony as a clarifying agent in photovoltaic (PV) glass in China is expected to surpass its use in flame-retardants in the very near future.
According to smelter sources, PV glass makers have a relatively high tolerance to price increases for antimony, because sodium antimonate only accounts for a small percentage of their total production cost. “We have seen the sign of cooling down in demand with recent tariffs from the US aiming to reduce imports of Chinese solar PV panels.
Last year, solar PV installations in China reached record levels. Since then, Chinese antimony smelters have focused on processing the raw material into sodium antimonate – which is used in PV glass to improve the efficiency of solar panels, rather than making ingot for conversion into antimony trioxide to be used in flame retardants.

Antimony (Sb) is used in the glass to improve stability of the solar performance of the glass upon exposure to ultraviolet (UV) radiation and/or sunlight. However, glass constitutes 5 % only of the end uses of antimony; most of it is used in flame retardants and lead-acid batteries.
Solar cells are characterized by temperature-dependent current–voltage, external quantum efficiency, and deep-level transient spectroscopy measurements. In this paper, the first thin-film solar cells based on a planar Sb 2 S 3 absorber grown from antimony ethyl xanthate (SbEX) by ultrasonic spray pyrolysis in air are demonstrated.
