Indian Scientists Develop Lead-Free Perovskite Photodetector

Recently, Indian scientists achieved a major breakthrough by developing an organic-inorganic halide perovskite self-powered broadband photodetector, addressing environmental concerns associated with the toxic lead component.

  • Scientists at the International Advanced Research Centre for Powder Metallurgy & New Materials (ARCI), Hyderabad, have successfully replaced toxic lead (Pb2+) in halide perovskite with magnesium (Mg), an abundant and non-toxic alkaline earth metal.
  • The organic-inorganic halide perovskite, specifically MAPbI3, has been a frontrunner in optoelectronic research, with applications in solar cells, LEDs, and photodetectors.
  • Lead's harmful effects on health and the environment have been a significant drawback in the use of hybrid perovskite, prompting researchers to explore ....
