It is costly! and the photovoltaic cells' production growth has been constrained by a shortage of purified polysilicon. In 2006, half the available quantity has been used by the PV Cell industries.
But times are changing:
PV cells prices will fall 40% within the next three years.
Leading manufacturers have increased dramatically their productions. Notably, China passed the US and become the third largest producer of PV cells, just after Germany and Japan.
Manufacturers found ways to use polysilicon more eff View the rest of this article
