A study by A*STAR Institute of High Performance Computing in Singapore has found that using a layer of graphene could be more efficient and cost effective than a layer of idium tin oxide (ITO) traditionally used in the production of solar panels.
Graphene allows more than 97% of light to pass through it, regardless of its wavelength; while ITO blocks certain wavelengths more than others. There are also limitations when using ITO because it is very brittle and becoming more expensive. As graphene production improves, there is the potential that only one or two sheets of the material would be needed to replace ITO in solar panel production, creating a more efficient and cost effective product.
