Scientists at Uppsala University in Sweden have announced a groundbreaking achievement in solar cell technology, setting a new world record for copper indium gallium selenide (CIGS) solar cells with an impressive efficiency of 23.64%. This remarkable milestone surpasses the previous record of 23.35% established in 2019 by Japan’s Solar Frontier.
New Solar Cell Efficiency Record
The researchers at Uppsala University have achieved this record-breaking efficiency by utilizing a novel approach in the manufacturing process of CIGS solar cells. By meticulously optimizing the deposition and annealing conditions of the CIGS thin-film, they were able to enhance the material’s properties, leading to improved light absorption and charge carrier collection.
Implications and Future Outlook
This groundbreaking achievement paves the way for further advancements in solar cell technology, ultimately leading to more efficient and cost-effective renewable energy solutions. The researchers are excited about the potential of this technology to contribute to the global transition towards sustainable energy sources, helping to address the pressing challenges of climate change and energy security.
