READLONDON: The paint on your wall could soon power your home by generating electricity from sunlight. Interestingly, it could even change colour on request if you find it tiring to stare at the same shade.
British scientists have found that combining the wonder material 'graphene' with other stunning one-atom thick materials could create the next generation of solar cells and optoelectronic devices. The breakthrough, published in the journal Science on Friday, could lead to electric energy that runs entire buildings by sunlight absorbed by its exposed walls.
The energy can also be used at will to change the transparency and reflectivity of fixtures and windows depending on environmental conditions, such as temperature and brightness. The isolation of grapheme led to the discovery of new family of one-atom-thick materials
