Solar cell technology developed by New Zealand's Massey University’s Nanomaterials Research Centre will enable New Zealanders to generate electricity from sunlight at a 10th of the cost of current silicon-based photo-electric solar cells.
The synthetic dyes are made from simple organic compounds closely related to those found in nature. The green dye is synthetic chlorophyll derived from the light-harvesting pigment plants use for photosynthesis. Other dyes being tested in the cells are based on haemoglobin, the compound that give blood its colour.
