Imagine a power station that’s literally sprayed onto your roof —and could match the colour of your tiles.
Thin film solar cells are thinner, cheaper and more versatile than the traditional silicon solar panels. Spray-on solar is a next step in the evolution of on-site power generation.
“These cells can be made with semiconductor dye materials, so you can match them to any colour or pattern you like—they’ll just convert that part of the solar spectrum into electricity. In the future we could have billboards that act as solar panels,” says Dr Gerry Wilson of CSIRO’s flexible electronics team.
