All solar cell efficiencies at a glance – updated
The research group led by Professor Martin Green has published Version 62 of the solar cell efficiency tables. There are 21 new results reported in the new version, a record number for the Tables.
Lhyfe launches world’s first offshore hydrogen project
Lhyfe has started producing offshore hydrogen via a pilot project in France, and Toyota and its partners have agreed to invest in hydrogen in Thailand. The Australian authorities, meanwhile, have approved a hydrogen project in Victoria.
Solar-driven photoreactors to generate hydrogen on rooftops
Scientists led by the Karlsruhe Institute of Technology have designed panel-like photoreactors relying on a water-splitting photocatalyst that could produce hydrogen on rooftops or dedicated solar farms. They claim the photoreactors have high economic potential because of their ‘extremely’ low costs.
Germany seeking proposals for 10 GW of solar factories
Solar manufacturers have until Aug. 15 to submit PV factory proposals to the German authorities.
Panasonic introduces new home battery
Panasonic’s EverVolt home battery supports DC and AC coupling for new and existing solar arrays.
Global sodium-ion battery market expected to reach $2.6 billion by 2028
The global sodium-ion battery market will grow at 16.2% annually to touch $2.6 billion by 2028. Major drivers include an increasing demand for these batteries as a lithium battery replacement for renewable energy storage and the growing trend towards low-speed electric cars.
New technique to repair solder interconnection failures in solar panels
Researchers in Japan have developed a repair technique for solar modules with damaged busbars and solder ribbons. They claim the new method can be implemented on site, without removing the panels from the array.
China solar module prices keep diving
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
‘Oversupply is a natural challenge to our industry,’ says Trina Solar official
Helena Li, president of Trina Solar’s global cell and module business, spoke to pv magazine at the recent SNEC trade show in Shanghai about the PV industry’s oversupply challenge. Li said the company is considering opening a factory in Europe and expressed optimism about future cost and price declines.
Keep your solar cells dry
Scientists in Norway used various imaging and characterization techniques to analyze the cells and other components of silicon PV modules that had been installed in the field for more than 10 years. The group’s aim was to isolate the role of moisture in various mechanisms that cause performance loss over time, and to understand how these mechanisms progress over long-term installation in real outdoor conditions.
