More stable and efficient materials for solar cells are needed in the green transition. So-called halide perovskites are highlighted as a promising alternative to today’s silicon materials. Researchers at Chalmers University of Technology, in Sweden, have gained new insights into how perovskite materials function, which is an important step forward.More stable and efficient materials for solar cells are needed in the green transition.
