2D Perovskites for Solar Cells and LEDS
University of Surrey researchers have developed strategies to improve the physical properties of 2D perovskite called Ruddlesde-Popper which can lead to the development of low-cost solar energy and LEDs. The study analysed the effects of combining lead with tin inside the structure to reduce the toxic lead quantity. This allows for the tuning of key properties such as the wavelengths of light that the material can absorb or emit at the device level-improving the performance of photovoltaics and light-emitting diodes. Three-dimensional perovskites have proved themselves remarkably successful materials for LED devices and solar panels in the past decade.
