## [Will lead-free Perovskite solar cells lead the future?](https://blog.delmic.com/to-lead-or-not-to-lead-will-lead-free-perovskite-solar-cells-lead-the-future)

Perovskite solar cells could spur the growth of solar power, but they currently contain lead, which is toxic. Recently, scientists have started to explore lead-free alternatives that are more environmentally friendly. Could the future be free of lead?
