The revolutionary compound graphene is able to convert a single photon of light it absorbs into multiple electrons that could drive electric current. This discovery makes the material an important alternative material for light detection and harvesting technologies based on conventional semiconductors like silicon. From this theory, graphene may be the future of solar energy - as it multiplies the Power of Light.
A paper published on May 2nd 2013 in the journal 'Science' by researchers at the University of
Manchester and the National University of Singapore showcase extending the usefulness of graphene molecules in modern day engineered building structure applications. Their theory is that covering entire sunlight exposed sides of buildings with graphene and other coated materials could make these building walls generate energy from the sunlight they absorb.
This is theoretically possible due to the physical and chemical characteristics of graphene. Graphene is the thinnest, strongest and conductive material on the planet (ref). Graphene is a 2D crytal that possesses ideal properties that include conduction, and insulation -- ranging from being opaque to completely transparent. "We are sure that as we research more into the area of 2D atomic crystals we will be able to identify more of such complimentary materials and create more complex heterostructures with multiple functionality. This is really an open field and we will explore it." Said Professor Antonio Castro Neto, Director of the Graphene Research Center at the National University of Singapore (ref).Added to the hope for cheaper and more efficient materials for photovoltaic applications, other uses of this technology expand to smartphones, drug delivery and computer chips. Graphene on building surfaces can help control temperatures within the building by being transparent or reflective as environmental conditions change.
