NPC Incorporated, Gosan Tech partner on perovskite solar module manufacturing
The alliance aims to utilize Gosan’s advanced inkjet printing technology in the manufacturing of perovskite modules, mainly for the Japanese and US markets.
Using Asterisk Sudoku for PV system reconfiguration under shading conditions
Researchers in Qatar have used an algorithm relying on a variant of the popular logic-based puzzle to determine the optimal way to eliminate cluster shading. They have tested the new approach under fixed and moving shadows.
The Hydrogen Stream: Japanese researchers develop green rust catalyst
Japanese researchers have developed a green rust–based catalyst for sodium borohydride, while South Korean scientists have created a framework to assess liquid hydrogen storage tanks for unmanned aerial vehicles (UAV).
Korean scientists achieve 21% efficiency in polycrystalline solar cell for underwater environments
The cell was fabricated with a 2.3 nm-thin layer of gallium oxide, a silver busbar aimed at improving charge collection and silicon nitride anti-reflection coating. It was encapsulated within a watertight 3D-printed box to ensure impermeability.
The Hydrogen Stream: Japanese researchers develop low-temperature hydrogen battery
Institute of Science Tokyo researchers proposed a battery with magnesium hydride (MgH2) as the anode and hydrogen (H2) gas as the cathode. Meanwhile, researchers at Chung-Ang University proposed chloride-resistant ruthenium (Ru)-based nanocatalysts for direct electrolysis and hydrogen production from seawater.
Photovoltaic trees can save forest cover
Research simulating a solar tree farm within a coastal forest in South Korea found that solar tree structures could preserve 99% of forest cover when compared to a fixed solar farm built in the same area, without sacrificing power output.
Korean startup developing perovskite-CIGS tandem solar technology for satellites
Flexell Space is planning to put its perovskite-copper indium gallium selenide (CIGS) tandem solar cell technology in-orbit later this year. It has also raised venture capital and signed several collaboration agreements, including a technology transfer with the Korea Institute of Energy Research.
LG and Octopus Energy to offer integrated heat pump solution in Europe
LG Electronics and Octopus Energy plan to launch a joint solution in Europe integrating LG’s high-efficiency heat pumps with Octopus’s AI-driven Kraken platform to accelerate sustainable heating adoption.
South Korea urges US to exempt firms from polysilicon tariffs
South Korea’s Ministry of Trade, Industry and Energy (MOTIE) is urging the United States to exempt its companies from Section 232 polysilicon tariffs, warning that restrictions could disrupt $2.8 billion in US solar investments.
Scientists build bifacial CIS solar cell with record efficiency, power density
Researchers in South Korea have demonstrated a lower temperature process for bifacial copper, indium, selenium (CuInSe₂) solar cells with a rear-side efficiency of 8.44% and 15.30% on the front. The device has been developed for applications in tandem solar cells.
