钙钛矿型太阳能电池以其高的能量转换效率和全固态结构，引发了新型光伏器件的快速发展。为此，它们对于各种可穿戴和便携式电子设备特别有用。现在首次通过将对齐的多壁碳纳米管片电极连续缠绕到纤维电极上来制备具有柔性纤维结构的Percent太阳能电池;通过溶液过程将光敏钙钛矿材料掺入其中。纤维状钙钛矿太阳能电池表现出3.3%的能量转换效率，其在弯曲时保持稳定。钙钛矿太阳能电池纤维可以通过成熟的纺织技术编织成用于大规模应用的电子纺织品。
Perovskite solar cells have triggered a rapid development of new photovoltaic devices because of high energy conversion efficiencies and their all-solid-state structures. To this end, they are particularly useful for various wearable and portable electronic devices. Perovskite solar cells with a flexible fiber structure were now prepared for the first time by continuously winding an aligned multiwalled carbon nanotube sheet electrode onto a fiber electrode; photoactive perovskite materials were incorporated in between them through a solution process. The fiber-shaped perovskite solar cell exhibits an energy conversion efficiency of 3.3%, which remained stable on bending. The perovskite solar cell fibers may be woven into electronic textiles for large-scale application by well-developed textile technologies.
