Dye-sensitised solar cells seek to mimic photosynthesis
Dye-sensitised solar cells seek to mimic photosynthesis. The dye acts like chlorophyll, the pigment that makes plants green and that is responsible for absorbing sunlight and liberating electrons. The electrons are passed via a semiconductor to an electrode, through which they leave the cell. By using a dye called phthalocyanine, which absorbs not only visible light but also infra-red wavelengths, Dr Grätzel has been able to raise the efficiency of the process to 11%. That, he says, should b - Read More

Cheaper photovoltaic energy from dye-sensitised solar cells
A cheap alternative to silicon solar cells can be found in dye-sensitised solar cells. This type of cell imitates the natural conversion of sunlight into energy by, for instance, plants and light-sensitive bacteria. Annemarie Huijser has succeeded in substantially improving a process in this type of solar cell, which is similar to the more widely known Grätzel cells. - Read More
