Flexible solar cells could be applied in fields such as satellites, airships, drones, individual soldier equipment, building integrated photovoltaics (BIPV), and wearable smart devices, which indicates great prospects. This paper introduces cell structures, fabrication methods and current statuses of four types of flexible solar cells respectively, including the flexible silicon thin film solar cell, the flexible CdTe solar cell, the flexible CIGS solar cell, and the flexible perovskite solar cell. This paper also analyses the key issue of efficiency improvement and the main problems in the industrialization of the flexible solar cells. Ultimately, the paper proposes suggestions from aspects of substrate development, efficiency improvement and industrial fabrication.
