The Korean manufacturer and the German research centre were able to improve the performance of their jointly developed tandem solar cell by almost one percentage point.

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 synthesise nitrogen and sulfur co-doped carbon-based anode material, which displayed great potential for seawater batteries.

Researchers at the Australian National University say they have set a perovskite solar cell efficiency record at 22.6%. This efficiency, however, appears to be lower than that achieved in January by a group of Swiss and Korean researchers who used quantum dots to achieve an efficiency of 25.7% in an area of 0.08cm2 and 23.3% in 1cm2.

While there are still many uncertainties as to the way in which hydrogen trade might evolve and change economic ties and political dynamics between countries, experts agree that green hydrogen can bring winds of change to the global energy arena. According to the International Renewable Energy Agency, significant geoeconomic and geopolitical shifts are just around the corner.

LG Chem’s energy storage and battery division’s US$10.7 billion (AU$14.8 billion) initial public offering received a staggering response from institutional investors, Reuters has reported.

Korea Zinc, non-ferrous metal smelting company, has agreed to invest $50 million in Energy Vault, a Switzerland-based gravity storage specialist, in order to use its tech to decarbonise its refining and smelting operations in Australia.

Hydrogen is frequently touted as a major player in decarbonisation, and it is. But it will only be used at scale much later, and at a much lower level than solar and wind.

The 41 MW facility was built by Korean developer Scotra with solar modules provided by South Korea-based manufacturer Hanwha Q-Cells. It was deployed on a water reservoir at the Hapcheon dam, in the South Gyeongsang province.

The continuous rise in solar panel prices may affect PV projects of up to 1 MW tendered by the Korea Energy Agency and the domestic solar module industry may not be able to provide the necessary production capacity to respond to the recent supply bottleneck.
