New Zealanders develop cheaper solar cells
This new technology uses a range of colored dyes in dye- sensitized solar cells.
This should make it cost 1/10 the expense of current technology.
Solar cell technology developed by the University’s Nanomaterials Research Centre will enable New Zealanders to generate electricity from sunlight at a tenth of the cost of current silicon-based photo-electric solar cells.
Additionally, these new cells are plentiful, renewable and non-toxic.
Dr Campbell says that unlike the silicon-based solar cells currently on the market, the 10x10cm green demonstration cells generate enough electricity to run a small fan in low-light conditions – making them ideal for cloudy weather.
He says the green solar cells are more environmentally friendly than silicon-based cells as they are made from titanium dioxide – a plentiful, renewable and non-toxic white mineral obtained from New Zealand’s black sand.
