Joe Biden guarantees to make photo voltaic modules extra environmentally pleasant – watts with that?
Guest essay by Eric Worrall
h / t ResourceGuy; If you thought that silicon or gallium arsenide doped with arsenic was bad on your roof, how about solar cells made from organic lead compounds or cadmium telluride? Biden’s quest for cheaper solar power examines some really terrifying photovoltaic innovations.
The US pledges to cut solar energy costs by 60% in a decade
Fri March 26, 2021
March 25 (Reuters) – The Biden government set a goal on Thursday to cut solar energy costs by 60% over the next decade by 2035 as part of an ambitious plan to decarbonise the US energy sector.
The US Department of Energy said the goal would accelerate its previous utility-scale solar cost target by five years. In order for the US power grid to run entirely on clean energy within 15 years, a key pillar of President Joe Biden’s climate change agenda, solar energy must be installed up to five times faster than today, according to the DOE.
To get there, the agency pledged to spend $ 128 million on technology, including Perovskite solar cells, which are seen as a promising cheap alternative to the market-dominating silicon cells. The funds will also support research Cadmium telluride and concentration of solar technologies.

Rechargeable batteries included cadmiumit was discontinued because cadmium is terribly toxic. Less than half a gram of cadmium in your system is going to really mess up your day. Symptoms include cancer, cadmium blues (persistent flu-like symptoms), kidney failure, softening of the bones, emphysema, and respiratory damage. Can you imagine having several pounds of cadmium on your roof? What if your neighbour’s solar powered roof catches fire?
Tellurium is uncomfortable, although it doesn’t seem as toxic as cadmium. At the very least, people seem to be recovering from tellurium poisoning. Clinical features of acute tellurium toxicity are metallic taste, nausea, vomiting, blackened oral mucosa and skin, and corrosive injury to the gastrointestinal tract from acidic solvents. … Our patients exhibited many of the hallmarks of tellurium toxicity, namely vomiting, garlic odor of breath, blackened oral mucosa, and benign clinical course. – Source https://pediatrics.aappublications.org/content/116/2/e319
Cadmium telluride Solar cells – double the fun when a house fire spreads the sheet material in your neighborhood. I don’t eat a cake from this apple tree.
The Perovskite solar cells are when something is possibly worse. From Wikipedia: – A. Perovskite solar cell ((PSC) is a type of solar cell that contains a compound with a perovskite structure, most commonly a hybrid organic-inorganic material based on lead or tin halide as a light-harvesting active layer. Perovskite materials such as methylammonium lead halides and purely inorganic cesium lead halide are inexpensive to manufacture and easy to manufacture.
Bio lead is likely the worst form of lead exposure as it is fat soluble. Organic lead is packaged neatly to ensure optimal absorption into your body and brain tissues. You don’t even have to ingest or breathe it – organic lead can get right through your skin, it just has to touch you.
From Wikipedia;
… Lead poisoning can cause a variety of symptoms and signs that vary depending on the person and the length of time they have been exposed to lead. The symptoms are non-specific and can be subtleand someone with elevated lead levels may not have symptoms. Symptoms usually develop over weeks to months if lead builds up in the body during chronic exposure, but acute symptoms can also occur from short, intense exposures. Symptoms from exposure to organic leadwhich is likely more toxic than inorganic lead occur quickly due to its lipid solubility. Organic lead poisoning has symptoms predominantly in the central nervous systemsuch as insomnia, delirium, cognitive deficits, tremors, hallucinations, and convulsions.
Symptoms can be different in adults and children. The main symptoms in adults are headache, abdominal pain, memory loss, kidney failure, male reproductive problems, and weakness, pain or tingling in the extremities.

There’s a reason governments are no longer allowing small amounts of organic lead to be added to gasoline.
The tin-based perovskite is probably the least offensive of the chemicals listed. Metallic tin is commonly used as a coating for food cans, although you can still experience acute toxicity from ingesting soluble tin salts, such as if there was a problem processing the food. But even if they opt for tin-based perovskite, who knows what the final recipe will be after they finish tinkering with the formula?
