MIT develops way to recycle old lead batteries to solar cells




Researchers at MIT have developed a method to reuse for the development of solar cells based on perovskite. Lead from old lead batteries This can prevent the toxic lead from the battery ends up in the environment.

The lead mainly from car batteries are currently recycled in the production of new lead-acid batteries, but with the advent of Li-ion batteries, which are used, including electric vehicles, this type of battery is less popular. It is still unclear what should be done. These waste stream over time

Researchers at MIT believe they can reuse in the production of a potentially promising type of solar cell in which the mineral perovskite is used, the lead well as writes The Washington Post. The required lead to such cells could be from old lead batteries recycled. The perovskietzonnecellen could be extended to some new solar panels. Following their lifespan in turn recycled This prevents the lead still ends up in the environment.

Perovskietzonnecellen stand for some time the interest of scientists, because this material in laboratories able to achieve efficiencies of over 16 percent, and such cells at lower cost to make, thanks to a simpler production. A typical silicon solar panel currently achieves an efficiency of between 15 and 22 percent. MIT thinks obtainable when perovskietzonnecellen returns of more than 20 percent.

Researchers see the potential of perovskietzonnecellen but include Dutch experts in the field of solar energy ECN signs that the solar cells is difficult for completely new species to conquer a spot. market Thus, these solar cells would have to prove in terms of longevity, performance and cost in practice. In addition, research is being done to lead perovskite solar cells in which tin is used.
