Published online 12 January 2021 Solar cells can now more efficiently capture light that bounces up from the ground and hits their undersides. Andrew Scott Michele De Bastiani (2021) Scientists have fabricated solar cells that efficiently gather energy from light that hits their undersurfaces, in addition to the conventional trapping of direct sunlight. The cells are based on a combination of conventional silicon semiconductor technology and materials called hybrid perovskites. “[Our solar cell] can perform more efficiently than any commercial silicon-based solar cell,” says Stefaan De Wolf of King Abdullah University of Science and Technology Solar Center in Saudi Arabia. De Wolf and his colleagues developed the technology in collaboration with research groups in Canada, Germany and Italy.
