New research shows viability of residential ice-source heat pumps
Scientists in the United Kingdom have demonstrated the feasibility of residential ice-source heat pumps in cold climates and densely populated areas. They designed a heat pump system that utilizes existing gas pipelines to transport water.
South Korea launches 1 GW PV tender
South Korea’s Ministry of Trade, Industry and Energy (MOTIE) has kicked off a tender for 1 GW of solar and 1.25 GW of wind. The ceiling prices for solar contracts stands at KRW 157,307 ($113.6)/MWh.
Turkey opens anti-dumping probe into Chinese PV frames, junction boxes
The Turkish authorities claim to have found evidence of dumping practices by Chinese PV junction boxes and frames manufacturers, which allegedly caused substantial damage to domestic producers.
MIT scientists developing silicon solar cell based on singlet exciton fission
Scientists in the United States have designed a microwire solar cell that could reportedly enable the coupling of singlet fission with silicon. Key to their achievement was an interface that transfers the electrons and holes sequentially into silicon instead of both at once.
EU introduces secondary legislation for Net-Zero Industry Act
The European Union has introduced secondary legislation under the Net-Zero Industry Act to support solar manufacturing. Member states must implement the new rules starting in 2026.
Perovksite-TOPCon tandem solar cell based on self-assembled monolayer achieves 31.1% efficiency
Researchers in China have fabricated a perovskite-TOPCon solar cell with a top perovskite device utilizing a self-assembled monolayer aimed to improved cell stability. The tandem cell achieved a high fill factor and a certified efficiency of 30.9%.
Aiko Solar wins second patent dispute against Maxeon in Netherlands
A Dutch court has rejected Maxeon Solar’s request for a preliminary injunction against China’s Aiko Solar in a dispute over EP2297788B1, a back-contact (BC) solar cell patent.
A closer, quick look at Longi’s world record back contact solar cell
pv magazine visited Longi’s booth at Intersolar in Munich and had a quick chat with Charles Yiang, President of Distributed Generation Business Group. He visually showed both sides of the 27.81% hybrid interdigitated back contact (HIBC) crystalline silicon solar cell that a few weeks ago achieved the world record efficiency for single-junction silicon solar cells.
TOPCon solar cell built with silver-doped nickel metallization achieves 23.66% efficiency
Scientists in Turkiye claim to have developed a nickel-based TOPCon solar cell with a minimal silver content and almost the same efficiency as fully silver metallized counterparts. The device uses a new nickel contact method that requires a trace of silver of only 0.5 mg/W.
Alpha launches residential heating solution combining heat pump, boiler
The UK-based company said its new hybrid solution includes a stand-alone monobloc air-to-water heat pump with a nominal capacity of up to 16 kW and one of its boiler range. The heat pump system uses R32 (difluoromethane) as a refrigerant and has a coefficient of performance of up to 5.1.
