Be Pink to be Green

A recent development in solar photovoltaic (PV) cells means that we could soon be seeing the cost of solar panels dropping considerably; making renewable electricity more affordable.

Currently, solar cells are among the most expensive renewable electricity generating technologies, but researchers at Ohio State University have developed a pink solar cell, which, while only half as efficient as standard cells, can be made at a quarter of the cost.

These new cells are known as dye-sensitized solar cells (DSSCs), and it is the red dye ruthenium which gives them their pink colour.
The research is now focussed on trying out different chemical compounds in order to increase the cells efficiency.
