Gallery: Graphene-Based Solar Cells Could Yield 60% Efficiency


Graphene model by James Hedberg

While silicon has long been the standard for commercial solar cells, new research from the Institute of Photonic Sciences (ICFO) in Spain has shown that graphene could prove far more efficient when it comes to transforming light into energy. The study found that unlike silicon, which generates only one current-driving electron for each photon it absorbs, graphene can produce multiple electrons. Though the application of graphene in solar cells is only theoretical, the potential outlined in the study is remarkable; solar cells made with graphene could offer 60% solar cell efficiency – double the widely-regarded maximum efficiency of silicon cells.

    If graphene has the capabilities that are touted here, it would seem perfectly reasonable for Tesla motors to explore the possibility of using thin graphene solar panels moulded into the roof and hoods of their electric vehicles to charge the cars batteries while driving or sitting…
