Sunbond unveils 550 W mono PERC modules

India’s Sunbond Energy has developed new mono PERC modules built with 144 half-cut M10 cells and 10 busbars. They are available in power outputs ranging from 520 W to 550 W, with efficiencies of 19.83% and 21.23%.

French rail operator to develop solar systems capable of operating at 9,000 V

SNCF Réseau and the National Institute for Solar Energy (INES) in France have agreed to jointly develop renewables projects. They aim to build PV systems that can supply continuous power at voltages of 3 kV, 6 kV, and 9 kV, while optimizing installation costs – particularly with regard to cables, operations, and maintenance.

Longi claims world’s highest efficiency for p-type, indium-free HJT solar cells

Longi said it has achieved a 26.56% efficiency rating for a gallium-doped, p-type heterojunction (HJT) solar cell and a 26.09% efficiency rating for an indium-free HJT cell, both based on M6 wafers. Germany’s Institute for Solar Energy Research in Hamelin (ISFH) has confirmed the results.


BIPV shading estimation methods key for uptake, says IEA-PVPS

A recently published report from the IEA-PVPS on building integrated photovoltaics (BIPV) digitalization found many BIPV professionals are unsure of a suitable method for estimating shading in BIPV projects.

3D electronics printer has potential to reshape solar and storage

Australian startup Syenta has developed a 3D printer capable of printing highly complex and functional electronics like photovoltaics, batteries, sensors and more, promising to do so in ways that are faster, cheaper and use less energy.

New method brings durability of perovskite solar cells closer to silicon

Researchers from the United Kingdom, the United States and Australia have reportedly developed a perovskite solar cell with comparable stability and durability to commercial silicon PV cells. They used a high-temperature processing method with dimethylammonium chloride to control the intermediate phases of perovskite crystallization.


New process increases efficiency of CIGS bifacial thin-film solar cells

Researchers from the Swiss Federal Laboratories for Materials Science and Technology (Empa) have developed a new low-temperature production process for bifacial thin-film solar cells based on copper indium gallium diselenide (CIGS). It resulted in record yields of 19.8% for front lighting and 10.9% for rear lighting.


Emporia unveils residential battery inverter solution

US-based Emporia Energy has developed a home battery system with an inverter and transformer. The lithium iron phosphate (LFP) battery has a storage capacity of 8.2 kWh, and up to six modules can be combined for up to 49 kWh of energy storage. The inverters come in 7.6 kW or 9.6 kW versions.


The Hydrogen Stream: Hydrogen production set for Tasmania

As Australia’s hydrogen project pipeline doubles in 12 months, Iberdrola announces investment in a green hydrogen and green methanol production plant in Tasmania. Meanwhile, projects in Scandinavia target the shipping industry.


New record for fastest single-charge solar EV over 1,000 km claimed

A solar-powered electric vehicle, designed and built by students of Australia’s University of New South Wales, has claimed a provisional Guinness World Record by going 1,000 km on a single charge in under 12 hours.
