Double-layered anti-reflective coating for heterojunction solar cells
South Korean scientists have developed a novel coating that purportedly reduces average cell reflectance and significantly increases short-circuit current. The coating is based on aluminum oxide and indium tin oxide.
Four-terminal heterojunction perovskite tandem solar cell with 30.09% efficiency
Developed by a Vietnamese-Korean research group, the complex PV device was built with a bottom bifacial crystalline silicon perovskite-filtered heterojunction sub-cell that is able to absorb all solar spectra in the short-wavelength range.
The Hydrogen Stream: Air Liquide eyes South Korea as Cummins announces fuel-cell truck plans
With Australia prepping plans for vast green hydrogen and ammonia production facilities, two of the country’s state governments are trying to drum up the end-user market as agreements are signed to drive use of the gas in Ukraine and Poland.
‘Polysilicon shortage will continue through 2021’
The latest global PV industry outlook published by trade group SolarPower Europe, has indicated tight supply of the solar panel raw material is expected to persist this year but the trade body said it would be unlikely to drive further price rises.
South Korea allocates 2 GW in PV tender, final average price drops to $0.118/kWh
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.
