ENG: Researchers from the Institute of Chemical Research of Catalonia (ICIQ) in Spain have developed innovative micromotors designed to autonomously purify wastewater. These micromotors generate ammonia in the process, which can be utilized as a green energy source. To enhance the efficiency of these micromotors, an artificial intelligence (AI) method developed by the University of Gothenburg is being employed. This AI technology aims to optimize the micromotors for the best possible purification outcomes.

ENG: Perovskite solar cells designed by a team of scientists from the National University of Singapore (NUS) have attained a world record efficiency of 24.35% with an active area of 1 cm2. Perovskites are a class of materials that exhibit high light absorption efficiency and ease of fabrication, making them promising for solar cell applications. In the past decade, perovskite solar cell technology has achieved several breakthroughs, and the technology continues to evolve.

ENG: An international team of physicists, chemists and biologists, led by the University of Cambridge, was able to study photosynthesis – the process by which plants, algae and some bacteria convert sunlight into energy – in live cells at an ultrafast timescale: a millionth of a millionth of a second. Using ultrafast spectroscopic techniques to study the movement of energy, the researchers found the chemicals that can extract electrons from the molecular structures responsible for photosynthesis do so at the initial stages, rather than much later, as was previously thought.

ENG: Scientists from Helmholtz Zentrum Berlin (HZB) could significantly improve on the efficiency of perovskite/silicon tandem solar cells. Prof. Steve Albrecht and his team used an advanced perovskite composition with a very smart interface modification. The lead authors, postdocs Dr. Silvia Mariotti, and Dr. Eike Köhnen, developed an interface modification to reduce charge carrier recombination losses and applied detailed analysis to understand the specific properties of the interface modification. These developments were then successfully implemented in tandem solar cells, and with help of Master’s student Lea Zimmermann, combined with further optical improvements.
