Yet,
cadmium telluride commands only about 30 percent of the thin - film market, according to DoE statistics, compared with amorphous silicon cells (such as those produced by Sharp and ECD Ovonics), which account for more than 60 percent; CIGS cells make up just about 1 percent of this market.
Harvey, who has an impressive
command of technical data, worries that toxic
cadmium telluride used in the thin - film panels will escape into the environment, and he isn't soothed by Chevron's assurances that it will spray polymer - based binders on the disturbed soil to keep it from blowing around.
