V-shaped PV system for agrivoltaic applications
An Italian startup supported by a group of scientists is developing a V-shaped agrivoltaic system that can reportedly find optimal application with bifacial modules and single-axis tracking. The proposed system configuration is claimed to reduce land use by 24 % compared to conventional setups.
Copeland invests in thermo-acoustic heat pump developer
The U.S. heating specialist has agreed to invest an unspecified sum in Dutch startup Blueheart Energy, which is developing a 6 kW heat pump that works on acoustic waves and is able to produce both heat and cold air.
Using surplus solar power to pre-cool, pre-heat homes
Scientists in Australia have shown how pre-cooling and pre-heating could be implemented in Australian buildings with the support of excess solar power. Their analysis has demonstrated that summer has the highest potential for air conditioning demand reduction.
TCL launches TCL SunPower Global unit
The Chinese group announced the new TCL SunPower Global unit will operate mostly in Europe, the Middle East and Africa, selling SunPower-branded solar energy solutions alongside TCL’s own solar products.
The impact of ice balls on PV module hailstone safety standards
Researchers in Switzerland have investigated the impact behaviour of ice balls on an aluminium Hopkinson bar at different velocities, diameter and temperature.
TOPCon solar cell based on aluminum contacts achieves slightly lower efficiency than silver-based counterpart
Researchers in Australia have have fabricated an aluminum contact-based TOPCon solar cell based that achieved a power conversion efficiency of 22.92%. The device was built with an aluminum contact manufacturing process that reportedly does not compromise the surface passivation quality of underlying silicon oxide layers.
Pathway to commercialization of aqueous sulfur-based redox flow batteries
Researchers in China have identified a series of engineering strategies to bring aqueous sulfur-based redox flow batteries closer to commercial production. Improving catalyst design, ion-selective membranes, and device integration will be key to solve this battery storage technology’s issues.
