A research team headed by Rui Wang at Westlake University has achieved a significant milestone in the realm of flexible tandem solar cells. By seamlessly integrating perovskite and copper indium gallium selenide (CIGS) materials, they have attained a remarkable photoelectric conversion efficiency of 23.4%. This groundbreaking work has been featured in the prestigious journal Nature Photonics. These cells are not only thin and lightweight but also highly flexible, with a thickness comparable to that of a human hair. This makes them ideal candidates for a myriad of applications, including construction, automotive, and aerospace industries.
