The lead solution to solar power

Lead recycled from millions of vehicle batteries can be converted into organolead perovskite materials for use in solar panels a team from Massachusetts Institute of Technology has demonstrated. The team's perovskite photovoltaic materials are formed as a thin film just half a micrometer thick, this implies that a single discarded car battery would yield enough lead to build solar panels to power thirty households. Given that there are hundreds of millions of vehicles on the roads most of which use a lead-acid battery that has a limited lifespan that is a substantial number of solar panels that might be made from a recycled metal. Moreover, at their end of life, the lead can be retrieved and used once more to fabricate new panels. Optimization of both process and panel are underway.
