Durability tests of perovskite solar cells under high-intensity monochromatic LED light, including UV light, were carried out. The spectral sensitivity characteristics of encapsulated perovskite solar cells were examined by exposing them to high-intensity monochromatic LED light (365 nm, 530 nm, 750 nm) at 100 mW/cm². Degradation of the perovskite solar cells was observed at specific wavelengths during these irradiations. Additionally, a monochromatic light accelerated test was conducted by varying the light intensity to confirm the degradation of the encapsulated perovskite solar cells. The light output of the LEDs was adjusted using a silicon solar cell which was measured with a solar simulator calibrated at AM1.5G, 100 mW/cm². The adjustment was made by matching the short-circuit current of a silicon solar cell under monochromatic LED light to achieve the same photocurrent output.
