The ultra-thin perovskite solar cells on plastic substrates with a thickness of several microns have attracted great attention nowadays as lightweight and large-area power sources for space applications thanks to their lightweight, flexibility, and high efficiency. This presentation aims to analyze the bending stability of ultrathin, flexible n-i-p structure perovskite solar cells. By introducing photoluminescence (PL) and electroluminescence (EL) methods for evaluating solar cell durability, we successfully demonstrate real-time measurements of the crack-propagating characteristics of ultra-thin perovskite solar cells with bending deformation during stretching-cycle test.
