Professor Peng Huisheng of the School of Polymer Science of our school recently adopted a new method of superimposing fabric electrodes to successfully fabricate fabric solar cells. These cells can be braided into various fabrics and provide a new type of wearable electronic device. The effective method. According to reports, the latest research work was published online on the Angew. Chem. Int. Ed., the top authoritative journal in the field of international chemistry. The first author of the paper was Dr. Pan Shaowu, a doctoral student of the research group. The article was named Hot Paper (Hot Paper) after its publication. At the same time, the journal also conducted a special press release under the title Wearable Solar Cells. This is also the group's follow-up on a stretchable linear supercapacitor in December 2013. The special issue was awarded by the journal.
On May 30th, Science magazine further reported on this research work with the theme of Weaving solar energy into fabrics, which triggered the attention of many academic and public media around the world.
Wearable devices are the mainstream development direction of today's electronic devices. In addition to meeting their own functions, these electronic devices also need to be lightweight, flexible, and woven. In recent years, there have been many attempts to produce linear micro-cells, which are lighter and more woven than traditional planar structures. These linear devices can be woven into various fabrics through textile technology, but it is still difficult to technically fabricate linear solar cells into fabrics.
Prof. Peng Huisheng’s research group made further breakthroughs on the bottleneck of the technology based on the research of the previous linear solar cell. First, they adsorbed the photoactive material onto the titanium silk fabric as a working electrode, and then the oriented carbon nanotube fibers with excellent mechanical and electrical properties were used as the counter electrode. Finally, two fabric electrodes were subtly added and electrolysis was added. After liquid encapsulation, fabric solar cells are obtained.
It is reported that once this new technology is introduced to the market, it will greatly change the daily electricity consumption mode of today's mankind, and it will play a solar charging advantage in the field trips, scientific expeditions, and other circumstances to avoid the shortage of power and the search for power. The easy-to-wear, zero-burden, low-cost fabric equipment will also be integrated with fashion design trends, using the unique dyes of the battery itself to bring a dual experience of technology and beauty.
