Elsewhere, Chinese researchers have synthesized ultrafine Pd100-xCux nanodot-modified TiO2 photocatalysts that display optimized energy barrier for interfacial hydrogen desertion, which reportedly exhibits excellent H2-evolution activity and stability, and Mitsubishi Heavy Industries has presented its plans to establish the Takasago Hydrogen Park, calling it the world’s first center for validation of hydrogen-related technologies, from hydrogen production to power generation.

The Korean manufacturer said its solar module business will be closed by the end of June. It blamed uncertainties in the global solar industry for its decision.

Korean researchers have built a CISSe solar cell that can be used as a bottom cell for applications in tandem cells with a top cell based on perovskite. In the manufacturing process, they replaced the vacuum technology with air annealing and the result was a record-breaking efficiency combined with potential lower production costs.

The Q.Peak Duo XL-G11.3 panel is currently the largest and most powerful panel produced by the Korea-based manufacturer. It features a temperature coefficient of -0.34% per degree Celsius and comes with a 25-year linear performance warranty.

Korea Electric Power Corp. plans to build solar on highways in two 20MW stages, followed by a third phase, under a government program to facilitate the development of energy-independent roads.

The Q Peak Duo XL-G10 panel series is based on monocrystalline ‘Qantum’ half cells and is the company’s first panel relying on M6 wafers.

The triple-junction solar cell is based on indium gallium phosphide (InGaP), gallium arsenide (GaAs), and Germanium (Ge) and is made with a micro-grating made of glass, consisting of a two-dimensional x-framework structure fixed onto the surface of the solar cell. Its operating temperature was found to be 6 degrees Celsius lower than that of a reference cell without the cooling technique.

Hyundai wants to use a partnership with South Korean PV equipment supplier Jusung Engineering to commercialize solar modules based on 24.45%-efficient heterojunction solar cells.

Scientists in South Korea developed a porous carbon material that, when applied as a coating to the separator film in a lithium-sulfur battery, was shown to reduce an unwanted side effect and improve the battery’s performance and reliability. The coating is based on methylene blue, a type of salt commonly used in textile dying.

Scientists in Korea have developed an efficient synthesis route to produce a novel co-doped anode material for rechargeable seawater batteries. They developed a one-step plasma-in-liquid process to synthesize nitrogen and sulfur co-doped carbon-based anode material, which displayed great potential for seawater batteries.
