Coupling balcony solar panels with residential storage

South Korean researchers have tested four operational modes to combine residential batteries with balcony PV modules and have found that the best configuration is when solar is supplied to the load after the battery is fully charged. Charging the battery with the grid prevents the risk of full discharge in the absence of PV power, they said.

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.
