Portable electronic devices with standalone power sources are increasingly demanded. Flexible photovoltaics devices for solar energy conversion remain the most attractive option to cater for this demand. Flexible solar cells have the advantages of light-weight, roll-to-roll processing, conformability, bendability and wearability. Following the excellent power conversion efficiencies (PCEs) of perovskite solar cells (PSCs) on rigid substrates, flexible perovskite solar cells (flex-PSCs) have gained remarkable research attentions. Successes have been recorded for flex-PSCs with conversion efficiency reaching 17.3%. Attainment of commercialization of flex-PSCs and integration into electronic gadgets require proper materials selections and processing techniques coupled with good resistance to deformation and long-term durability. This work reviews (i) comprehensively, materials and processing techniques used for the fabrication of flex-PSCs; (ii) mechanical tolerance of flex-PSCs and (iii) stability of flex-PSCs in different environmental conditions.

具有独立电源的便携式电子设备的需求日益增长。满足这种需求的用于太阳能转换的柔性光伏器件仍然是最有吸引力的选择。柔性太阳能电池具有重量轻，卷对卷加工，贴合性，可弯曲性和耐磨性的优点。继刚性衬底上的钙钛矿太阳能电池（PSC）出色的功率转换效率（PCE）之后，柔性钙钛矿太阳能电池（flex-PSC）受到了广泛的研究关注。flex-PSC取得了成功，转换效率达到了17.3％。实现flex-PSC的商业化并集成到电子产品中，需要适当的材料选择和加工技术，并具有良好的抗变形能力和长期耐用性。这项工作（i）全面审查了制造flex-PSC所用的材料和加工技术；（ii）flex-PSC的机械耐受性和（iii）flex-PSC在不同环境条件下的稳定性。
