Nanoelectronics research center imec has presented what is thought to be the first-ever semi-transparent perovskite PV-module, achieving power conversion efficiencies up to 12%. This technology may enable semi-transparent PV-windows and other such advanced applications. Moreover, combining these semitransparent perovskite modules with Si solar cells, an unprecedented 20.2% in power conversion efficiency for a perovskite/Si stacked solar module was achieved.

The semi-transparent perovskite modules of imec realized by scalable coating techniques showed efficiencies of 12% on sizes as large as 4 cm2 and 10 % on sizes as large as 16cm2, a world-best achievement in this domain.

Researchers at the University of Washington, the Massachusetts Institute of Technology and the University of Oxford have been trying to find ways to repair inherent perovskite defects in order to improve the efficiency of solar cells. They showed that the photons they shined on the perovskite cells had a therapeutic effect, and exposure to intense visible light increased the energy conversion efficiency of the perovskite crystals.

Using perovskite crystals synthesized at Oxford University, the scientists showed that intense light exposure helped crystals repair themselves by physically transporting iodine during illumination. They used two powerful imaging techniques to show that iodine ions within perovskite crystals moved away from intense light.

This new book describes both the crystallography and properties of perovskite related materials. It further describes the practical applications in solar cells, microelectronics and telecommunications. The book draws on materials science, chemistry, physics, and geology, and contains problems and answers to enhance knowledge retention.

Scientists at Syracuse University and Brookhaven National Laboratory found a new way to visualize and monitor chemical reactions in real time using perovskites. They have designed a nanomaterial that changes color when it interacts with ions and other small molecules during a chemical reaction, allowing to monitor reactions qualitatively with the naked eye and quantitatively with simple instrumentation.

The researchers explain that many chemical reactions occur in a solution that is colorless and transparent so the only way to know if a reaction has occurred or not is to perform extensive analysis after a multi-step purification. This new method represents a simpler way to investigate why and how fast a reaction occurs (if at all). The group has designed a nanoparticle that reacts with by-products of the reaction. When the reaction occurs, the nanoparticle fluoresces at a different color, allowing to gauge kinetics by eye, instead of using special equipment.
