Solar cells are one of the most ‘easy-to-apply’ forms of renewable energy. However, their efficiency is still low when compared to their cost. Researchers from the Institute of Photonic Sciences in Spain have developed a graphene-based solar cell which they believe has 60% efficiency in converting sunlight to energy. The pure carbon substance is capable of absorbing a large spectrum of light and converts it to energy efficiently. However, researchers are still looking for a solution to extract the energy from the graphene cell. Solar cells may become the main form of renewable power if a solution to this issue is found.
