Inner Mongolia Energy Group switches on 1.6 GW solar farm in northern China
Inner Mongolia Energy Group has turned on a 1.6 GW solar project in Bayannur, Inner Mongolia, using inverters from China’s Sineng Electric.
GCL claims 19.04% efficiency for perovskite solar panel
The Chinese manufacturer was able to increase the panel efficiency from 18.04% to 19.04% in 16 months. The panel has a size of 2,005 mm x 1,005 mm x 35 mm and a weight of 34.5 kg.
Heterojunction solar cell based on indium tin oxide buffer layer achieves 25.36% efficiency
Researchers in China have sought to increase the efficiency of heterojunction solar cell through a buffer layer made of indium tin oxide. This innovation reportedly resulted in a 0.1% efficiency increase deriving from optimized short-circuit current density and fill factor.
Dutch homeowners file suit over 2027 phase-out of net metering
Around 137,000 Dutch homeowners have filed a legal claim seeking compensation over the planned cancellation of net metering in 2027.
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.
