Qcells hits 28.6% efficiency with scalable perovskite-silicon solar cell
South Korea-based solar module manufacturer Qcells has set a new efficiency world record for a commercially scalable perovskite-silicon tandem solar cell, produced at its pilot line in Germany.
The Hydrogen Stream: new model and repository for accurate pre-feasibility studies
European researchers have told pv magazine that hydrogen production costs are often underestimated in prefeasibility studies, while the South Korean authorities have reported a rise in deals for large-scale hydrogen consumption projects.
Standalone liquid air energy storage system for power, heating, cooling supply
Korean scientists have designed a liquid air energy storage (LAES) technology that reportedly overcomes the major limitation of LAES systems – their relatively low round-trip efficiency. The novel system enhances efficiency by increasing power output through the generation of thermal energy using natural gas as the external fuel during energy release.
KRICT sets world record with 20.6% efficiency for large-area perovskite cells
The Korea Research Institute of Chemical Technology (KRICT) has set a world record for power conversion efficiency at 20.6% for large-area perovskite solar cells exceeding 200 cm². The result, confirmed by Germany’s Fraunhofer Institute for Solar Energy Systems ISE (Fraunhofer ISE), marks a significant milestone in solar cell technology.
Hybrid perovskite-organic solar cell reaches record-breaking efficiency of 24%
Korean scientists have fabricated a perovskite-organic solar cell with a uniform sub-nanometer dipole layer. The device recorded a power conversion efficiency of 24% under testing, a new record for lead-based hybrid perovskite-organic solar cells.
Japanese scientists build stretchable organic solar cell with 14.2% efficiency
Researchers in Japan have built a stretchable organic solar cell than can ensure high efficiency levels while preventing crack initiation and propagation. The cell was built with a hole transport layer based on PEDOT:PSS treated with a new additive type.
The Hydrogen Stream: UK to fund 11 green hydrogen projects
The UK government has confirmed new hydrogen plans, while RWE says it has secured construction and environmental permits to build a 100 MW electrolyzer in the Netherlands.
South Korea launches 1 GW solar tender
South Korea’s Ministry of Trade, Industry and Energy (MOTIE) has kicked off a tender for 1 GW of solar and 1.8 GW of wind. The ceiling prices for solar contracts stands at KRW 157,307 ($113.69)/MWh.
Argentina inaugurates first commercial lithium hydroxide production plant
Part of mining company POSCO Argentina’s Sal de Oro integral lithium project, the plant was inaugurated at the General Güemes Industrial Park in the city of Salta. It is estimated to produce 25,000 tons of lithium hydroxide per year.
Perovskite solar cell built with slot die coating achieves 19.17% efficiency
A team from Jeonbuk National University in South Korea used slot die coating (SDC) to produce uniform high-quality perovskite films, which they used in a perovskite solar cell that achieved 19.17% efficiency and lab cell-sized modules that achieved 17.42% efficiency.
