Dye-sensitised solar cells

The video above shows how we can convert solar energy into electrical energy using a dye-sensitised solar cell.

Dye-sensitised solar cells

Dye-sensitised solar cells (DSSC) are a relatively new and low-cost type of photovoltaic devices. They can convert solar photons to electrons with close to 100 % efficiency, at the peak absorption wavelength, although their overall efficiencies are still significantly lower than the silicon cells you may have on your house today.

Dye-sensitised solar cells have the benefits of being low cost to manufacture, can be made using earth abundant materials – even be assembled using materials found in a typical household – and can be made on flexible substrates.

While this type of solar cell is not yet efficient enough to be deployed at a large scale, it is hoped that continued research and development will make this happen in the future.
