Description:

The operational stability of encapsulated perovskite solar cells (PSCs) is imperative for their commercialization. Here, we have investigated the degradation of PSCs with organic (PTAA) and inorganic (NiOx) HTLs under light and thermal stress. The device parameters under 1-sun illumination were monitored over time at different temperatures; 20 to 85oC. The device degradation kinetics has been discussed by adopting the Arrhenius model with temperature and humidity prefactor correction. The temperature-dependent device parameters analysis showed a lower value of degradation activation energy for the device with the PTAA (∼ 0.274 eV) than that for the NiOx device (~ 0.495 eV).
