A European project aims to develop flexible tandem perovskite-CIGS solar technology to make 25%-efficient 100 cm2 modules with a variety of substrates for decentralized solar PV applications. The project entails using processes that are scalable for roll-to-roll production.

Sunairio has launched software that features high-resolution historical climate data and high-resolution future climate models to provide insights into site-specific risks. It recently raised venture capital to expand into new markets for its solar and wind portfolio-oriented software.

Swiss-based Hive Power has launched Flexo to optimize grid-connected devices, enabling flexibility in markets with dynamic tariffs. The Flexo solution has interfaces to integrate inverters, home energy management systems, charging point managements systems, meters, and other internet of things (IoT) devices.

Researchers in Switzerland investigated different setups to maximize energy yields per area for PV Systems on flat roofs. Their work revealed that using horizontal single-axis tracking and reflectors could add up to 5% greater performance.

Researchers from Belgium and the University of Cyprus have completed outdoor stability tests of perovskite solar mini-modules providing two-years of data on stability performance. The tests showed that the modules’ performance loss rates during the burn-in period of perovskites ranged between 7% and 8% per month.

European researchers are developing miniaturized space propulsion technology that is propellant-free and based on electrodynamic tethers integrating perovskite-copper indium gallium diselenide (CIGS) tandem solar cells. It is meant to maneuver satellites in space or in de-orbiting without relying on heavy propellants on board.

India’s solar panel supply chain map, recently updated by Hong Kong-based quality assurance firm Sinovoltaics, identifies 111 production sites with a combined PV module manufacturing capacity of 58.4 GW. An additional 60 GW is set to come online between 2027 and 2030, raising announced capacity expansions to 119 GW.

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.

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.

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.
