Fig. 21. (a) Dependence of OSC power conversion efficiency (PCE) on the ALD deposition temperature of the Al2O3 gas-diffusion barrier (GDB), (b) normalized PCE of OSCs with and without Al2O3 GDB during continuous operation in ambient air and (c) the normalized PCE of encapsulated OSCs stored under ambient and damp-heat (70 °C/70% RH) conditions without illumination.205.
