Maltese scientists design offshore virtual power plant integrating PV, wind, storage
The proposed virtual power plant (VPP) integrates a platform-to-ship (P2S) setup to electrify anchored and bunkering ships, while also providing surplus electricity to the country’s grid. The system was designed to operate through a 200 MW floating wind farm and a 300 MW floating PV plant, with battery and compressed air systmes being used for energy storage.
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.
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.
