Abstract:

Solar energy is an ideal alternative of fossil energy, almost inexhaustible and not harmful to the environment. In recent years, there has been a great deal of interest and progress in the development of solar cell devices in the form of fibers. Compared with flat solar cells, fibrous solar cells have the advantages of easy preparation, good flexibility, three-dimensional light exposure and so on. They can be made into flexible solar cell fabrics by weaving technology and integrated into clothing to charge portable electronic products such as smart bracelets. In particular, fibrous perovskite solar cells have increased their photoelectric conversion efficiency from 3.3% to 15.7%. In this paper, the background and advantages of the rise of fiber cell devices are briefly reviewed, and the structure and working principle of planar and fibrous perovskite solar cells are compared. Then, the latest research progress of fibrous perovskite solar cells is reviewed from two aspects of preparation method and structure design. The characteristics of different preparation methods are compared and different structure design methods are introduced. The weaving technology is described in detail from the aspects of weaving method, construction of conductive tracks into textiles and connection technology. Finally, the challenges in this field are summarized and the future development direction and application prospect are prospected. It is hoped that this paper can attract scholars from different research backgrounds to enter this multidisciplinary field, and promote its development and create a real era of smart wearable.
