A study by researchers at the US Department of Energy’s Oak Ridge National Laboratory takes a fresh look at what could become the first step toward a new generation of solar batteries. The study examines the structure of metal halide perovskites, materials promising for their ability to turn light into electric energy, known as photovoltaic conversion. The study relied on the comprehensive expertise and state-of-the-art equipment of ORNL’s Center for Nanophase Materials Sciences, or CNMS, to ...
