a breakthrough in solar technology with the use of synthetic chlorophyll
derived from the light-harvesting pigment plants use for photosynthesis.
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.
“The expected cost is one 10th of the price of a silicon-based solar panel,
making them more attractive and accessible to home-owners.”

solar panel manufacturing using CIGS which is another substance that is
cheaper and more efficient than silicon panels. This product is being
manufactured at present and the company says the panels will be
available this summer.
