Professor Peng Huisheng from our university's School of Polymer Science recently introduced an innovative approach by stacking fabric electrodes, successfully creating fabric solar cells. These groundbreaking devices can be woven into different types of fabrics, offering a new kind of wearable electronic technology. The research was published online in *Angew. Chem. Int. Ed.*, one of the most prestigious chemistry journals globally. The paper, authored by Dr. Pan Shaowu, a doctoral student in Professor Peng’s group, was quickly recognized as a Hot Paper and even received a special press release titled "Wearable Solar Cells." This marks the group’s continued success following their earlier work on stretchable linear supercapacitors, which had also been highlighted by the journal.
On May 30th, *Science* magazine covered the research under the theme "Weaving Solar Energy into Fabrics," drawing widespread attention from both academic and public media around the world.
As wearable electronics become increasingly popular, there is a growing demand for devices that are not only functional but also lightweight, flexible, and easy to integrate into daily wear. In recent years, researchers have explored linear micro-cells as an alternative to traditional planar structures, aiming for better flexibility and ease of weaving. However, fabricating linear solar cells into actual textiles has remained a significant challenge.
Building upon previous research on linear solar cells, Professor Peng’s team made key breakthroughs. They first coated titanium silk fabric with a photoactive material to serve as the working electrode. Then, they used carbon nanotube fibers—known for their excellent mechanical and electrical properties—as the counter electrode. Finally, by carefully aligning the two fabric electrodes and encapsulating them with electrolyte liquid, they successfully created flexible fabric solar cells.
Once this technology reaches the market, it could revolutionize how people use electricity in daily life. It would offer a reliable power source during outdoor activities, field trips, or scientific expeditions, eliminating the need to search for power sources. The fabric-based solar equipment is not only easy to wear and cost-effective but also has the potential to merge with fashion trends. The unique dyes of the battery itself could create a beautiful fusion of technology and style, offering users a dual experience of function and aesthetics.
