Solar power breakthrough at Massey
New solar cells developed by Massey University don't need direct sunlight to operate and use a patented range of dyes that can be impregnated in roofs, window glass and eventually even clothing to produce power.
Researchers at the centre have developed a range of synthetic dyes from simple organic compounds closely related to those found in nature, where light-harvesting pigments are used by plants for photosynthesis.
Dr Campbell said that unlike silicone-based solar cells, the dye- based cells are still able to operate in low-light conditions, making them ideal for cloudy climates.
They are also more environmentally friendly because they are made from titanium dioxide - an abundant and non-toxic, white mineral available from New Zealand's black sand. 858
