Scientists have found a way to make tin-based perovskite solar cells more efficient and longer-lasting by adding a specially selected molecule during manufacturing. Metal halide perovskite solar cells are considered promising alternatives to conventional silicon solar panels. They can be lightweight, flexible and relatively inexpensive to produce. Their shape can also be adjusted for use […] The post Tiny Additive Makes Lead-Free Perovskite Solar Cells Last Longer appeared first on Knowridge Science Report .
