First attempt to fabricate solar cells based on antimony selenoiodide
South Korean scientists have produced a solar cell based on antimony selenoiodide, with a 4.1% efficiency, a short-circuit current density of 14.8 mA cm2, an open-circuit voltage of 473.0 mV, and a fill factor of 58.7%. They claim the cell exhibits excellent stability in humid conditions.
A 15.2%-efficient solar cell that you can fold in half
Scientists in South Korea developed a foldable thin-film device with some promising characteristics. Integrating a perovskite cell material and a carbon nanotube electrode, the group fabricated a device that achieved 15.2% efficiency and could withstand being folded more than 10,000 times at a bending radius of 0.5mm.
Hybrid tandem perovskite solar cell with 18.04% efficiency
South Korean researchers claim to have developed a PV cell with a higher efficiency rate than any other tandem cell based on perovskite and organic materials.
Jenny Chase predicts up to 194 GW of solar this year
Falling module prices will help PV post another record year after an estimated 132 GW was installed worldwide in 2020, according to an energy transition investment trends report published by Bloomberg New Energy Finance.
WoodMac predicts 30% drop in Asia-Pacific front-of-meter battery costs by 2025
A new Wood Mackenzie report suggests that costs for front-of-the-meter battery storage systems in the Asia-Pacific region could fall by 30% by 2025. The declining costs are already having a palpable impact, as 2021 has opened with a slew of large-scale battery project announcements.
South Korea may tender 4 GW of solar PV this year
The Korea Energy Agency (KEA) will likely launch two 2 GW tenders in April and October. These will include the procurement of large-scale solar PV parks for the first time.
Australian iron ore producer, South Korean steelmaker agree to green hydrogen future
Fortescue Metals Group Chairman Andrew ‘Twiggy’ Forrest returned to Western Australia last week after a four-month worldwide search for green energy projects and resources. One of the deals secured on the trip was a circular green hydrogen partnership with South Korean steelmaker Posco.
South Korea opens its renewable energy market to PPAs
Power purchase agreements will be allowed between renewable energy producers owning plants with a capacity of more than 1 MW and electricity consumers. Local utility Kepco, however, will keep serving as an intermediary.
New solar window tech with 2.1% efficiency
Researchers in South Korea have fabricated a fully transparent solar cell which they claim has a transmittance for visible light of more than 57%. The integrated device generates enough power to move a small-sized motor.
Semitransparent bifacial CIGS cell with 10.5% efficiency
The solar cell was developed by Korean scientists for power-generating window applications. They built the device with transparent conducting oxide (TCO) rear contacts and a textured polydimethylsiloxane (PDMS) layer with light-scattering and antireflection properties.
