China’s Haitian Group to buy PV business from Heraeus for $68.6 million
China’s Haitian Group has agreed to acquire Heraeus’ photovoltaic silver paste business for $68.6 million, including 100% equity in Heraeus Photovoltaics (Shanghai), Heraeus Photovoltaic Technology (Shanghai), and Heraeus Photovoltaics Singapore.
Chinese institutes create new metrological traceability system for silicon, perovskite solar cells
China’s Fujian Metrology Institute (FMI) and the National Photovoltaic Industry Measurement and Testing Center (NPVM) have created a metrological traceability system for both silicon and perovskite solar cells. The calibration system consists of a monochromatic light system, a bias light system, a 3D-motion measurement platform with temperature control, and an electrical measurement system.
Sekisui Chemical launches pilot perovskite PV projects in Japan
Japanese plastics manufacturer Sekisui Chemical, which recently invested in a 100 MW perovskite solar production plant, announced its latest demonstration project at two sites owned by Japan’s MUFG Bank. The project aims to both raise awareness of practical applications of perovskite solar PV technology and to further verify durability, weather resistance, and performance.
The best hole transport layers for perovskite solar cells
An international team has combined organic synthesis with predictive models to discover new functional materials that enhance performance of hole transport layers used in perovskite solar cells. The team asserts that optimizing for other solar cell properties is possible with the platform, as well as using it for development of materials for other kinds of devices.
Chinese PV Industry Brief: Maxeon, Tongwei reach patent dispute settlement
Maxeon Solar Technologies and Tongwei have settled a global patent dispute over shingled solar cell and module technologies, ending litigation initiated by Maxeon in Germany in 2023.
New research sheds light on impact of sodium-induced degradation in heterojunction solar cells
University of New South Wales researchers investigated the impact of sodium-induced degradation in heterojunction solar cells under accelerated damp-heat testing. They considered three different types of sodium salts and identified the degradation mechanisms attributed to each contaminant.
REC Silicon shuts down polysilicon operations at U.S. site
The reason given for the shutdown is the inability to “improve the level of some key impurities,” and would not be able to deliver a quality product in the time demanded by the company’s main customer.
IEA-PVPS shares guidance on technical KPIs for PV systems
The International Energy Agency’s (IEA) Photovoltaic Power Systems Programme (PVPS) highlights key performance indicators (KPIs) for PV systems in its latest report. It calls for clear KPI definitions and standardized data handling to enhance system efficiency and reliability.
Perovskite solar cell based on hole-selective interlayer achieves 26.39% efficiency
Researchers in China claim to have built a perovskite solar cell that can effictively reduce ion migration and offer superior stability. The device utilizes an ultrathin membrane made of a polymeric material known as PDTBT2T-FTBDT (D18), which reportedly offers conformal coverage on the surface of perovskite film due to its high fluidity.
