Oak Ridge National Labs researchers use ZEISS ORION NanoFab SIMS to characterize perovskite photovoltaic films
Solar cells made out of a perovskite-structured compound are the fastest-growing solar technology to date. Compared to traditional silicon solar cells, the raw materials used are cheap to produce, simple to manufacture, and their efficiencies are very high making them commercially attractive and a very promising material for high-efficiency optoelectronic applications. However, some of the physical and chemical properties of these materials, which are critical to improving performance, are still not fully understood. Very recently, researchers from the US Department of Energy’s Oak Ridge National Laboratory in Tennessee have employed a unique combination of imaging and characterization tools and atomic-level simulations to solve a longstanding debate about the internal structure of these fascinating materials.
