One of my teachers mentioned it to me in one of my classes so i thought i might have a look.
"Solar Paint
Solar Paint is an environmentally friendly solar cell technology that will allow every household in Australia to generate their own electricity, affordably and sustainably.
The invention involves the development of a completely printable organic solar cell based on semiconducting polymer nanoparticles dispersed in water. Essentially these tiny particles in suspension are a water-based paint, which can be printed or coated over large areas. In the first instance these coatings will be put onto plastic sheets that can be placed on the roof of a house. However, in the longer term it will be possible to directly paint a roof or building surface."

Efficiency readings are low (6-7%), but can be applied in wider areas.
