Fiber-shaped SolarCells: Structure, Performance, Limitations and Challenges

Solar cells always are considered as clean and low-cost resources of electrical energy by researchers. Typical solar cells are fabricated on inflexible and fragile of glass substrates. Theses solar cells have not performance in aspect of flexibility. So, design and fabrication of solar cells that are fabricated on flexible substrate are very important for researchers. Fiber-shaped solar cell is one of the flexible solar cells that is fabricated on flexible substrates such as metallic wires and polymeric fibers. These solar cells are divided to three groups: 1. Dye sensitized fiber-shaped solar cells 2. Polymeric fiber-shaped solar cells 3. Perovskite fiber-shaped solar cells. This paper briefly reviewed fiber-shaped solar cells, structure, performance, limitations and challenges in this field.
