Perovskite solar panels contain lead so you are going to have lead around, the question is if you can recycle the lead or if it goes in the environment.

Well there is always alternative number 3 - dont use perovskites.
Organic solar cell: https://en.wikipedia.org/wiki/Organic_solar_cell :

Perovskite solar cell: https://en.wikipedia.org/wiki/Perovskite_solar_cell :
> 29.8%
If you need to use ~1.5x more area, but you avoid leaking any heavy metals or similarly toxic materials - I would say that's a win.
Of course, there are other parameters to consider.
