Can car batteries be recycled into solar panels?

Bad news: Discarded car batteries contain a potential source of lead pollution.

Good news: Scientists have come up with a way to recycle the same batteries (or rather the lead) into new long-lasting solar panels which provide emissions-free power.

The win-win solution is based on developments in solar cells which makes use of a compound called perovskite – now as efficient as other methods for use in solar panels – which relies on lead.
