A research team from the Korea Institute of Materials Science (KIMS) has recently successfully developed a highly stable flexible perovskite solar cell that can be produced under normal humidity conditions, significantly reducing manufacturing costs. The related research findings have been published in the Chemical Engineering Journal.

Led by Dr. Dong-chan Lim and Dr. So-yeon Kim, the team innovatively addressed the moisture sensitivity issue of perovskite materials by adopting a two-dimensional perovskite interlayer structure. "This technology enables the production of high-efficiency perovskite solar cells without the need for expensive environmental control equipment," Dr. Lim stated. Tests showed that the cell maintained over 85% efficiency after 2,800 hours of operation in a 50% humidity environment.

The flexible solar cell also exhibited excellent mechanical performance, retaining 96% efficiency after 10,000 bending cycles. The research team further confirmed that the technology is applicable to large-area continuous production processes, demonstrating commercialization potential.

"The outstanding durability of flexible devices makes them ideal for wearable electronics and vehicle-integrated solar systems," Dr. Kim added. The study was conducted in collaboration with institutions such as the University of Fribourg in Switzerland, and the team plans to further develop next-generation solar cell materials adaptable to various environments.
