In a recent breakthrough study, scientists have discovered a key restriction in bismuth vanadate that could lead to more efficient solar cells. Bismuth vanadate is a type of perovskite, a material that is widely used in the manufacturing of solar cells. The research team, led by scientists from the University of Illinois at Urbana-Champaign, discovered that the material’s performance is limited by the number of electrons it can move through its structure. This limitation, known as Coulombic restriction, could potentially be overcome by altering the material’s composition or adding dopants, allowing for more efficient solar cells. The team’s findings could also have implications for other perovskite-based materials used in electronics and photovoltaics.

Scientists have made a major breakthrough in the field of solar energy: they have uncovered a key restriction in bismuth vanadate, a type of perovskite used in manufacturing solar cells. This restriction, known as Coulombic restriction, limits the number of electrons that can be moved through the material’s structure. By altering the material’s composition or adding dopants, this restriction could be overcome, leading to more efficient solar cells. This
