Radiative cooling tech based on polydimethylsiloxane film increases PV module generation by up to 3.72%
Scientists in China have proposed to use polydimethylsiloxane films doped with soda glass to reduce solar module temperature. The coating achieved solar transmittance of 94.8% and sky window emissivity of 95.3%.
Dual-axis solar tracker based on UV, MEMS sensors
Researchers have designed a new tracking system that utilizes an arithmetic optimization-based PID controller. The proposed tracker uses two different sensor types – a UV sensor and a micro-electromechanical solar (MEMS) sensor. The first one calculates the intensity of UV radiation received from the sun, and the second one forecasts the sun’s path across the sky.
JA Solar sues rival module manufacturer over TOPCon patent infringement
The Shanghai-based solar development company has filed two complaints with the Munich and Hamburg local divisions of the Unified Patent Court.
Hydronic closed-loop cooling system for photovoltaic modules
An international research team has developed a closed-loop PV cooling system that can reportedly offer 24-hour continuous operation. The system is claimed to be particularly suitable for hot and arid regions and to improve the lifespan of solar panels by up to 8.2%.
Weiheng Ecactus releases three-phase all-in-one battery storage system
The Chinese manufacturer’s new battery energy storage system consists of an inverter ranging in size from 5 kW to 13 kW and a storage system of 10 kWh to 30 kWh. Up to five units can be connected in parallel.
Chinese PV Industry Brief: Akcome provides update on restructuring process
The Chinese cell maker said its unit Zhejiang Akcome Photovoltaic Technology has received the green light for restructuring. However, if the reorganization is unsuccessful, the company will proceed to bankruptcy liquidation.
Solar cell based on 2D Dion-Jacobson perovskite achieves 19.11% efficiency
Chinese researchers claim to have developed an “ultrastable” perovskite solar cell based on a two-dimensional, Dion-Jacobson phase perovskite. The device was constructed with blade coating technology and is scalable, according to its creators.
Mibet releases mounting system for utility-scale PV
The Chinese company said its new GT1 product is made out of hot-dip galvanized Q235B steel and can withstand wind speeds of up to 60m/s.
New soiling detection method based on drones, AI, image processing
Developed by scientists in China, the proposed approach uses mathematical morphologies for image processing, such as image enhancement, sharpening, filtering, and closing operations. It also uses image histogram equalization and edge detection, among other methods, to find the soiled spot.
WTO accuses China of low transparency on state subsidies, including solar
The World Trade Organization (WTO) Secretariat has criticized China for an alleged lack of transparency in its state support framework and has urged the nation to improve its subsidy notification process.
