Scientists Boost Efficiency of Perovskite Solar Cells by 250% with a New Technique
Cheaper to produce and with an ability to absorb higher energy forms of light, Perovskite materials have the potential to replace silicon in solar panel technology.
However, scientists are still trying to figure a way to make perovskites more stable and long-lasting.
Scientists at the University of Rochester and the Chinese Academy of Sciences have figured out a way to increase the efficiency of a type of perovskite by 250%.
They achieved this by combining the perovskite with a substrate of metal instead of glass.
This method improves the interaction of the electrons within the perovskite, resulting in a boost in light conversion efficiency.
Perovskites are crystalline formations that may be a more efficient solution than silicon in solar cells and detectors.
Using a substrate of either a layer of metal or alternate layers of metal and dielectric material can increase perovskite's light conversion efficiency.
The metal substrate flips the set arrangements of electrons and their holes that are generated by the photons, resulting in increased efficiency.
Researchers are looking for alternatives to lead-halides due to their negative environmental impacts.
