Universal method to improve lifespan of lithium-ion batteries
Researchers at the Gwangju Institute of Science and Technology (GIST) have developed a broadly applicable and versatile post-electrode-engineering process. It can be applied to a range of conventional anodes to improve their stability.
Construction begins on South Korea’s largest PV project
South Korean utility Kepco is building a 200 MW solar park on a former salt farm. It said the project will be operational by June 2023.
South Korea kicks off 2 GW PV tender
Selected projects will be awarded a fixed rate under a 20-year contract under the country’s renewable energy certificate (REC) scheme and will sell electricity to local power distributors.
SDN launches 550W solar module with 21.28% efficiency
The Korean manufacturer launched a new bifacial module based on M10 wafers and is planning to produce bigger modules based on M12 wafers starting from the third quarter.
Test production starts at SolarEdge’s 2 GWh Korean battery cell fab
The inverter and battery manufacturer says its new Sella 2 factory will produce cells for its residential solar-plus-battery products as well as for other applications.
Hanwha Q Cells to build US solar module factory, expand cell capacity in South Korea
Hanwha Q Cells plans to build a 1.4 GW solar panel factory at an undisclosed location in the United States. It has also announced plans to expand its cell capacity to 5.4 GW in South Korea. CEO Justin Lee spoke to reporters at the Smarter E event about the company’s plans and current supply chain issues.
Q Cells, German researchers claim 28.7% efficiency for 2T perovskite-silicon tandem solar cell
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.
Doped carbon for a reliable lithium sulfur battery
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.
High performance seawater batteries based on novel anode material
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.
Australian researchers claim solar cell efficiency record
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.
