German BESSY II Research Reveals: Cesium Chloride Seed Layer Can Improve Quality of Perovskite-Silicon Tandem Solar Cells

A team from the Helmholtz-Zentrum Berlin (HZB) in Germany used the BESSY II synchrotron radiation facility to conduct nanoscale analysis of perovskite-silicon tandem solar cells fabricated by evaporation methods, and proposed a new approach to improve the quality of perovskite thin films. The study shows that introducing a thin cesium chloride (CsCl) seed layer between the two sub-cells promotes uniform growth of the perovskite layer while reducing undesirable lead iodide deposition at the interface. The research demonstrates that the cesium chloride seed layer improves the growth of the evaporated perovskite layer and reduces the formation of lead iodide. Scanning electron microscopy images show that the perovskite layer grown without a seed layer (left image) consists of extremely fine crystallites...

Canadian Light Source Synchrotron at University of Saskatchewan Receives $3 Million CAD in Upgrade Funding

On August 26, Innovation Saskatchewan announced that it will provide $3 million CAD in funding to the Canadian Light Source synchrotron at the University of Saskatchewan to support the installation of an advanced solid-state amplifier, advancing the facility's upgrade efforts. According to reports, this solid-state amplifier is a key component of the Canadian Light Source's core particle accelerator and will support the operation of its 22 synchrotron radiation beamlines. The upgrade is expected to enhance facility performance, operational reliability, and energy efficiency, further strengthening its capacity for cutting-edge scientific research. The Canadian Light Source is Canada's only synchrotron facility. Synchrotrons use electromagnetic fields and radiofrequency waves to accelerate electrons to near the speed of light, keeping them in a circular orbit; as electrons move, they generate high-brightness, highly focused synchrotron radiation beams, which are directed to different experimental beamlines to help researchers study material structures and properties at the atomic scale.
