Researchers in South Korea have analyzed the effects of alkali doping on the fill factor of kesterite solar cells and have built a device on a flexible metal foil optimized with a sodium fluoride doping layer.
The latest edition of the World Nuclear Industry Status Report indicates the stagnation of the sector continues. Just 2.4 GW of net new nuclear generation capacity came online last year, compared to 98 GW of solar. The world’s operational nuclear power capacity had declined by 2.1%, to 362 GW, at the end of June.
SK Group has been chosen as the preferred bidder to build a portion of the 2.1 GW floating solar complex the South Korean government is planning near the Saemangeum tidal flats, on the Yellow Sea coast.
The Korea Aerospace Research Institute has conducted a battery-powered test flight of solar-powered unmanned aerial vehicle EAV-3. The aircraft is powered by solar cells on its wings and body and an LG Chem lithium-sulfur battery.
Scientists in South Korea combined two processes to etch a nanostructure of tiny pyramids onto the surface of a silicon wafer. As well as trapping more light and increasing the cell efficiency, the group claims that its nanostructure improves the mechanical flexibility of the cells. This could potentially allow for the use of much thinner silicon wafers than is currently possible in production.
Researchers in South Korea have used the process to increase performance and the replicability of large-area organic cells. The method was used during film formation to speed up solvent evaporation.
The South Korean PV manufacturers is bringing its three most powerful solar panels to Europe. All of them are based on its Q.antum Duo Z tech, which reduces the gaps between cells and drives up module efficiency by 4% in relative terms.
The South Korean government has released a new roadmap to support R&D activities in the solar sector. The document indicates the country’s solar manufacturing industry may be encouraged to opt for high-efficiency and expensive panels based on tandem solar cells.
