Technology and R&D

Researchers in Germany have unveiled new high-efficiency, micro concentrator photovoltaics technology that taps established micro-components manufacturing processes to enable lower costs. A demonstrator relying on the micro-CPV module achieved efficiency of 36% based on IEC62670-3 concentrator standard test conditions.

Wuxi Dk Electronic Materials Co., Ltd. (DKEM) is acquiring a 60% stake in Solamet. The Chinese silver paste supplier says it aims to absorb Solamet’s patented solar paste technology and global client base amid mounting margin pressures.

Enel’s Pioneer project is expected to last 10 to 15 years and has been integrated with Rome-Fiumicino airport’s Solar Farm, self-consumption PV system.

Tesvolt and Samsung SDI have developed a 5.26 MWh containerized battery system for commercial and utility-scale applications in Europe. It supports multiple inverter brands and is designed for high levels of fire protection and cybersecurity.

The U.S. manufacturer said its new heat pump water heater can provide up to 60% more hot water than standard electric water heaters. The system is available in 240 V and 120 V options and with a capacity ranging from 160 L to 190 L.

The researchers said they optimized the low-bandgap inverted perovskite cells through a passivating aluminum oxide (Al2O3) interlayer deposited via atomic layer deposition (ALD), which significantly helped improve device efficiency.

pv magazine is compiling a guide to home solar installations, aimed at those who are interested in installing but are new to the market and want to make an informed decision. We have spoken to associations, installers and industry specialists in major solar markets across the globe to compile best practice guidance and advice that aims to be applicable to home solar installations anywhere in the world. 

Australian battery solutions provider RedEarth Energy Storage has announced an international partnership that will see it jointly develop an integrated hardware and energy management system combining solar, storage, and bidirectional electric vehicle charging capabilities in a single unit.

A digital product passport could support circular practices in the European PV industry by better tracking material composition, recyclability, and supplier information, crucial for material recovery.

The King Abdullah University of Science and Technology and the Fraunhofer Institute for Solar Energy Systems report producing perovskite-silicon tandem solar cells with open-circuit voltages exceeding 1.9 V as the result of a two-step hybrid evaporated/blade-coated process for perovskite films.
