The use of perovskites as light-harvesting layers has become an important technology for low-cost solar cells that are capable of converting more than 20 percent of sunlight into electricity. The basis for such solar cells are the properties of lead-based hybrid perovskite layers, including very high absorption of solar light and great electrical properties.
Unfortunately, as these products degrade, they create significant environmental concerns. This limits their potential for large-scale implementation. Therefore, researchers are working to develop lead-free metal halide perovskite materials and corresponding solar cell architectures to optimize their performance. Leaders of this program aim to achieve this by:
