An innovative study of two-dimensional (2D) materials from engineers at the University of Surrey could boost the development of next-generation solar cells and LEDs.
Three-dimensional perovskites have been a very successful product for LED devices and solar panels in the last decade. One key issue with these materials, however, is their durability, with machine performance declining faster than other modern materials. The engineering community believes that the 2D variant of perovskites could provide answers to these performance issues.
In a study published in Letters Journal of Corporate Chemistry, researchers from the Surrey Institute of Advanced Technology (ATI) describe in detail how you can improve the physical properties of a 2D perovskite called Ruddlesden-Popper.
The study analyzed the effects of lead mixing with tin within the Ruddlesden-Popper structure to reduce the toxic lead level. This also allows tuning key buildings such as the light waves that the material can absorb or emit at the device level – improving the performance of photovoltaics and light emitting diodes.
Cameron Underwood, lead author of ATI research and postgraduate researcher, said:
“It’s okay to get a lot of fun about the potential of 2D perovskites, as they can promote a sustainable turnaround in many industries. We believe that our analysis of perovskite performance enhancement can play a role in improving the sustainability of solar energy and low-cost LEDs. . “
Professor Ravi Silva, corresponding author of the research and Director of the ATI, said:
“As we move away from fossil energy sources to more sustainable alternatives, we are beginning to see innovative and innovative uses of materials such as perovskites. The Institute of Advanced Technology is committed to being a strong voice in shaping green and more sustainable. future in electronics – and our new analysis is part of this ongoing debate. “
