German company RENA Technologies has announced the first sales of a new tool for silicon cell manufacturing. The tool is used for etching/removal of unwanted material on one side of a solar cell, and will be integrated into the gigawatt-scale production of an unnamed manufacturer in South Asia working with TOPCon technology.

Researchers in China have found that the addition of serine cations to the electrode/electrolyte interface of aqueous zinc-ion battery could effectively inhibit zinc dendrite growth and enable a highly reversible zinc anode.

China Three Gorges Group has announced its latest PV module procurement results, while GCL-Si has revealed plans to raise CNY 5.8 billion ($812.9 million) via a private placement to finance its expansion.

Scientists in Korea have proposed to use an algorithm that simulates the behavior of foraging bees to shape a new grid-forming inverter design. The approach is designed for both grid-connected and islanded inverters.

China’s National Energy Administration (NEA) says the nation installed 78.42 GW of solar in the first six months of this year, bringing it to nearly 470 GW of cumulative installed PV capacity by the end of June.

JinkoSolar says that its solar panel shipments reached 30 GW in the first of this year.

Global demand for sodium-ion batteries is expected to grow to just under 70 GWh in 2033, from 10 GWh in 2025, at a compound annual growth rate (CAGR) of 27%, according to UK-based market research company IDTechEx.

A Chinese-Swiss research group has fabricated a 2D-3D perovskite solar cell with a world-record power conversion efficiency. The cell uses a 2D perovskite layer at the interface between the perovskite and the hole transport layer, which the researchers said can improve charge-carrier transport/extraction while suppressing ion migration.

CHN Energy has signed a deal to build 1 GW of offshore floating PV in China’s Shandong province, while JA Solar has announced plans to raise around CNY 9 billion ($1.3 billion) to support capacity expansion.

Chinese inverter manufacturer TSUN says its new balcony PV kit consists of one or two 20.7%-efficient solar modules, a 96.7%-efficient microinverter, a bracket, and cables.
