Description

technical field [0001] The invention belongs to the technical field of solar cells, and relates to a perovskite solar cell (PSC, Perovskite Solar Cells) and a preparation process thereof, in particular to a flexible perovskite solar cell and a preparation process thereof. Background technique [0002] With the rapid development of the field of near-space detection, airships, drones and other aircraft have been widely used. Taking airships as an example, lightweight and high-efficiency solar cells have attracted widespread attention as an ideal energy source for airships. Solar cells are usually laid on the skin surface of airships, and ordinary rigid solar cells cannot be installed on airships because their surfaces are usually curved. Therefore, airships, drones, etc. have an urgent need for flexible solar cells that are lightweight, bendable, and have high specific power. [0003] Flexible solar cells are solar cells prepared on flexible plastic or flexible glass substrat...
