A team from the University of Surrey has found that fusing a perovskite material with an element called ferrocene dramatically increases the efficiency of perovskite-based solar panels. The team found that the intended success was produced by focusing on the chemistry of the solar panels, rather than on other approaches that looked at mechanical and electrical components.

Thomas Webb, a postgraduate research student and project lead at the University of Surrey, said, “Our research quantifies these perovskite cells down to a minute level, focusing on chemical compounds and their specific problems. For example, common practice is to coat, Or the cells are ‘doped in lithium’, but the lithium absorbs water, leading to an increased energy loss over time.

“We discovered an element within organometallic chemistry called ferrocene that significantly improves efficiency and stabilizes the energy degradation that occurs over time in all solar panels; not to mention that it causes the water absorption problem.” Cheaper to produce and solve.”

Perovskite materials are widely considered to be the successor to silicon because they are lighter and much cheaper to produce. However, the promise of perovskite has yet to be realized due to the difficulty of replicating laboratory results in mass production.

Project lead Dr Wei Zhang from the University of Surrey said, “Silicon cells are efficient but costly to produce; perovskite materials are undoubtedly the next generation of photovoltaic technologies. There is still a long way to go to ensure these are widely implemented.” Can be done, but with these results, we are a generous step closer to making this a reality.”

Professor Stephen Sweeney, co-supervisor of the research from the University of Surrey, said, “This is an important development to advance this important new materials system at a time when reliable renewable energy sources are of vital global importance. It is also one of the partner universities.” A very satisfying example of how interdisciplinary research and complementary expertise in the U.S. has produced a high impact result.”

The project has been produced in collaboration with Imperial College London, University of Nottingham, University of London Southbank, University College London and Fluxim AG. research was published in advanced energy materials,
