The performance of solar cell newcomer materials called perovskites has soared in recent months. But they still have big problems when it comes to working in real-world settings. For starters, the best perovskites contain lead, which is highly toxic. Now, researchers have figured out how to make solar cells with lead-free perovskites. So far, the new devices arent as efficient as their leaded counterparts, but researchers are hopeful they will improve quickly and help propel perovskites into the marketplace.
