U.S.-based PeroNova is specialized in metal halide perovskite-silicon tandem solar cells made with its novel stability-enhancing interfacial treatment. It is targeting a range of applications including space and rooftop markets.
I’m more concerned with longevity and use of more environmentally friendly materials with solar panels than efficiency. In about 30 years or so, they reach their end of life so there will be hazardous waste resulting from that.
Remember that solar just doesn’t stop working at some random day. The efficiency drops to where it makes sense to replace then people like me come in and buy the panels for pennies on the dollar because a 18% efficient panel will work just fine.
Some solar panels are considered hazardous waste, and some are not
That’s horribly unspecific
Lead and cadmium
AFAIK in EU Leaded solder is forbidden since many years (outside of safety related equipment). Cadmium is regulated in similar fashion. Electronic equipment disposal and recycling is also strictly controlled.
Every few decades we would dump fields and fields of solar panels. I’m sure that’s not good for the environment. The heavy metals, batteries, manufacturing and transportation byproducts, even the plastics that could be used in packaging. Wish there was a better renewable energy solution with no waste.
Nobody talks about dumping these things in the field. Glass, silicon, and aluminum can be reused or disposed safely. As I said in previous post - in EU electronic waste is disposed properly without dumping whole things into a landfill. Solar panels aren’t even the hardest e-waste to deal with.

Will you be able to handle all these panels as it becomes economically reasonable for people to replace them?
What’s hazardous in the solar panels?

The whole thing looks like fear mongering.
