Scientists in South Korea developed a new electrode structure for a solid-state battery which they say could lead to both higher energy densities and simplified manufacturing processes for this promising energy storage technology.

Scientists in Korea have investigated performance degradation in quantum dot solar cells – an important consideration for a technology that has seen rapid efficiency increases in recent months. The group found surface oxidation of quantum dot material represents a significant threat to longer-term performance and the researchers suggest that an additional layer in the cell could solve the problem.

Scientists at South Korea’s Daegu Gyeongbuk Institute of Science and Technology have set a new efficiency record of 11.4% for a cell based on a copper zinc tin sulfide thin film applied to a flexible substrate.
