> In 2017, a study found that as much as 62% of the cadmium from cadmium telluride models were leached out at room temperature depending mostly on acidity of the solutions.[3] From the related article: "The pieces are cut out from modules of the four major commercial photovoltaic technologies: crystalline and amorphous silicon, cadmium telluride as well as from copper indium gallium diselenide." So they cut pieces from a sealed module? Seems unsurprising that leaching would occur when you cut pieces of a PV panel and expose it to acidic solution for an extended period. Functional installed solar panels are sealed behind a protective glass panel.
