Scientists in South Korea demonstrated a perovskite cell with a certified efficiency of 24.4%. The device is claimed to maintain over 80% of its initial efficiency after 1,300 hours in the dark at 85 degrees Celsius.

The South Korean module manufacturer has developed two new products for large-scale floating PV plants. They have power outputs of 415 W and 420 W and efficiencies of 19.4% and 19.6%.

Longi Solar had filed two lawsuits in China against the validity of two patents of the photovoltaic manufacturer from South Korea. Hanwha Q-Cells sees now a good chance of being successful in proceedings before the European Patent Office.

South Korean scientists have built a kesterite solar cell based on a zinc tin oxide (ZTO) buffer layer. It offers almost the same efficiency as kesterite cells based on toxic cadmium sulfide buffer layers, as the energy of the electrons between the kesterite absorber layer and ZTO buffer layer are aligned.

The centralized nature of policymaking in Beijing would enable component standardization to ease the transition from EV to stationary energy storage use, according to Greenpeace East Asia.

Re-elected South Korean president Moon Jae-in today declared he will follow-up on a campaign trail promise to eliminate carbon emissions by mid century. The announcement comes just two days after Japan’s new prime minister said he would accelerate his nation’s emissions target.

The South Korean manufacturer has launched a new 60-cell panel with a power output of up to 365 W. The 21.1%-efficient module features a 320 W microinverter with an efficiency of 97%.

The South Korean authorities plan to introduce new rules for PV waste recycling in 2023. Several recycling facilities are already being built, including one by the government, with a combined capacity of 9,700 tons.

Dozens of solar companies are claiming renewable energy certificates issued for “wood-burning” biomass technology are unconstitutional as most such facilities are fueled by wood pellets co-fired with coal in older power plants. A constitutional court decision is expected within two years.

Doubling down on renewable energy investment and energy transition spending is required to ensure a truly green global recovery from the Covid-19 crisis and its economic aftershock, claims the International Renewable Energy Agency.
