Seung Hun Lee, professor of physics and Joshua Choi, a professor of chemical engineering, are tweaking specific molecules of HOIPs
A group of scientists at the University of Virginia is investigating ways to increase the stability of organic-inorganic hybrid perovskite (HOIPs) crystal structures to extend the durability of such materials.
The team claims they have found a new way to better handle HOIPs, make them more efficient, and stay productive over time in changing conditions.
Rotating the HOIPs molecule is the key to prolonging the life of the electrons and increasing the energy conversion efficiency.The researchers used microscopic detection equipment and measurement techniques with high-performance computer simulations to observe the molecular structures of these materials that were mutated.The results showed that photo-induced electrons and holes Of the re-compound was screening inhibition, resulting in the formation of polaron to extend life expectancy, so they believe that the search to find a high temperature in a wide range of entropy entropy of organic - inorganic perovskite, solar cells may be to achieve excellence The key to performance.
The research team's current efficiency record for HOIP-based solar cells is above 22%, comparable to the efficiency of a standard silicon solar cell.
