Recently, a research team led by Professor Zhang Xiaohong from Soochow University has made a significant breakthrough by successfully developing flexible crystalline silicon-perovskite stacked solar cells. This achievement effectively tackles the key challenges related to efficiency and stability that have long plagued stacked flexible solar batteries.

By capitalizing on the spectral complementarity of crystalline silicon and perovskite materials, the newly developed battery has achieved a remarkable enhancement in photoelectric conversion efficiency. The theoretical upper limit of its efficiency surpasses 43%, marking a substantial leap forward in solar cell technology.

Moreover, the lightweight and flexible nature of these solar cells makes them exceptionally well-suited for a wide range of applications, particularly in spacecraft and space data centers, where weight and flexibility are crucial considerations.

The groundbreaking research findings have been published in Nature, one of the world's leading international academic journals, further solidifying China's position at the forefront of solar cell innovation.
