Since the breakthrough in power conversion efficiency when perovskite materials are used in planer‐type solar cells, researchers have tried to apply perovskite materials into fiber‐shaped solar cells in order to achieve higher power conversion efficiency. However, the difficulty of film fabrication on the fiber surface makes it difficult to obtain a high‐quality perovskite film layer, and to obtain a large improvement in performance. In this work, the vapor‐assisted deposition method is creatively applied in the preparation of fiber‐shaped solar cells, and realizing the purpose of growing a high‐quality perovskite film layer on the fiber substrate after some innovative changes are made to the fabrication processes. The power conversion efficiency of the finally obtained fiber‐shaped perovskite solar cell reaches 10.79%, which is currently the highest power conversion efficiency in the field of fiber‐shaped solar cells.
