The IEC/EN61215 and IEC/EN61730-certified panel features 144 half-cells based on M10 wafers and a 10-busbar design. Its operating temperature coefficient is -0.341% per degree Celsius and its power tolerance reaches up to 5%.

Scientists in Japan delved deep into the crystalline structure of a perovskite solar cell in order to understand how chlorine helps to improve the cells’ stability. By varying the concentration of chlorine in the material they were able to find an optimal level for increased stability, and open new doors on the way to understanding the specific role of chlorine and the mechanism behind the improvement.

The result is claimed to be the highest efficiency ever reached for a large-area, polymer film-based perovskite photovoltaic module. The device has an area of 703 square centimeters and was fabricated through a new coating method.

The portable module has a foldable design with a four-panel structure and a power output of 100 W. It also incorporates a Suncast module that indicates the best height and tilt angle it must have to ensure optimal yield.

Origin Energy, Australia’s biggest energy retailer, has agreed to team with Japan’s largest oil refiner, Eneos, to explore the potential for a commercial-scale green hydrogen supply chain between their respective home markets.

Next Energy and Marubeni are developing a blockchain tech for PV module inspection – with the support of the Japanese government – which they claim is able to provide data on a panel’s traceability and components as well as verifying that the data were not modified or tampered with.

Japanese scientists have developed a new lithium-sulfur battery by using titanium oxide and titanium nitride to prevent the formation of polysulfides during the fabrication process. This allows the battery to retain 85% of its capacity after 500 cycles at 2 C.

The latest update to the Photovoltaics Report produced by research organization the Fraunhofer ISE has offered up the usual slew of interesting stats on the state of solar across the continent.

Japan’s Ministry of Economy, Trade and Industry has released a draft energy plan with ambitious revisions to the nation’s previous energy and emissions targets. The proposed plan will sees a doubling of renewables compared to the previous target, and significant cuts to coal and gas, much of which it buys from Australia.

The latest global PV industry outlook published by trade group SolarPower Europe, has indicated tight supply of the solar panel raw material is expected to persist this year but the trade body said it would be unlikely to drive further price rises.
