Bluetti has unveiled a new portable, weatherproof power station featuring a lithium iron phosphate battery with 1,536 Wh of power capacity and a rated output of 2,400 W.

Researchers in China have developed a new chemical bath deposition technique to deposit tin oxide on a perovskite cell’s flexible substrate without requiring a strong acid. The resulting cell has achieved a certified efficiency of 24.90% and remarkable stability.

GCL SI says it will track carbon emissions from polysilicon production to module assembly and shipping. Each module will have a QR code revealing its specific carbon emissions, protected by blockchain tech to prevent tampering. It says this will offer transparency in preparation for looming Carbon Border Adjustment Mechanism (CBAM) rules.

Solplanet, a China-based inverter manufacturer, says its new three-phase hybrid inverter series includes four versions with power ratings of 25 kW to 40 kW. They feature efficiencies of up to 98.4% and a maximum input voltage of 1,100 V.

Astronergy has announced a 1 GW solar module deal with China National Petroleum Corp. The order is for its ASTRO N-Series modules, which feature its tunnel oxide passivated contact (TOPCon) 4.0 cell technology.

Huawei says its new, all-in-one storage solution for residential PV comes in three versions with one, two, or three battery modules, offering 6.9 kWh to 20.7 kWh of usable energy.

The Chinese Academy of Science has developed a new technique that uses non-toxic lemonene as a reagent to control the degree of EVA expansion during the decapsulation process of end-of-life photovoltaic modules. The proposed approach reportedly achieves the complete delamination of glass and backsheet without excessive damage to the solar cells

Researchers in China claim to have achieved the highest efficiency ever reported for perovskite solar cells based on “alternative” hole transport materials. The device reportedly offers improved hole extraction and significantly reduced charge recombination at the interface between the perovskite layer and the hole transport layer.

The new product combines the NEO 800TL-X Microinverter and the NOAH 2000 Battery. Up to four batteries can be stacked, for up to 8,192 Wh of storage capacity.

Researchers in China have designed an organic solar cell the uses an acceptor based on selenium as an alternative to commonly utilized non-fullerene acceptors. The new acceptor enabled the cell to have reduced non-radiative recombination loss and improved dielectric constant.
