Chemical reduction processes utilising the catalytic properties of aluminium and manganese can allow the purification processes to operate at much lower temperatures, and these new processes are now commercial available

New processes such as electrodeposition are now easily able to provide cheaper and more environmentally friendly puresilicon

Production of monocrystalline silicon is very energy intensive, and involves emissions of carbon.  There are emerging technologies for reducing carbon emissions and energy use, but they need to be improved if silicon production is to be completely sustainable

Polycrystalline cells have a lower embedded energy content and so are more efficient

With a single crystal of silicon, the bandgap is smaller, so the solar cell is more efficient

With a single crystal of silicon, the recombination losses are reduced so the solar cell is more efficient

With a single crystal of silicon, the bandgap is , so the solar cell is more efficient
