Scientists develop safer lead-based perovskite solar cell

Researchers at Northern Illinois University
have reported in the journal Nature on a potential breakthrough in the development of hybrid
perovskite solar cells. Considered rising stars in the field of solar
energy, perovskite solar cells convert light into electricity. They’re potentially cheaper and simpler
to produce than traditional silicon-based solar cells and have demonstrated comparable
efficiency levels. But key challenges remain before they can
become a competitive commercial technology. One major challenge is the use of lead. Most top-performing hybrid perovskite solar
cells contain water-dissolvable lead, raising concerns over potential leakage from damaged
cells. Lead leakage could be perceived as an environmental
and public health risk. The research team has developed a technique
to sequester the lead used to make perovskite solar cells and minimize potential toxic leakage
by applying lead-absorbing films to the front and back of the solar cell. Under conditions of severe solar cell damage
in a lab setting, the lead-absorbing films sequestered 96% of lead leakage. Their experiments further indicate the lead-absorbing
layers do not negatively impact cell performance or long-term operation stability.

  2. When finding out how solar cells is treated after use now.
    I realy think using led especially one that can go in contact with water. Is a baad idea.
    It's crazy enough som people are brainwashed to belive CO2 is a poison.
    But please don't kill ewerything with your stupiderty.
