>“One of the biggest drawbacks of using perovskite solar cells is
their impact on the environment. By enabling zinc and other non-toxic
metals to be used in the capping layer, our innovation potentially
solves a major obstacle that prevents the widespread use of perovskite
solar cells,” explained Dr Ye Senyun, research fellow from the NTU,
School of Physical and Mathematical Sciences, a lead researcher of the
study.

Hm, doesn't this just delay the environmental impact or slow it down?

What do you mean, are you referring to perovskite?

Perovskite solar cells could also be made so thin and flexible that they could be painted on windows, or entire facades in all sorts of colors. And because it is so light-sensitive, it is believed that in the future you could charge your mobile phone with ordinary indoor lighting if it was powered by perovskite solar cells.

My understanding is that they didn't get rid of the lead that was being used along the perovskite, they just sealed it with zinc and other materials too, or did I misunderstand?

Were solar cells not environmentally frinedly to start with?

Power of all kinds tends to have issues with it's materials.

There's a reason why metal is recycled.
