A method for enhancing the moisture barrier property of polydimethylsiloxane (PDMS) polymer films is proposed. This is achieved by filling the PDMS free volume with aluminum oxide (AlO  x  ). To deposit AlO  x  inside PDMS, thermal atomic layer deposition (ALD) is employed. The PDMS/AlO  x  film thus produced has a 30 nm AlO  x  layer on the surface. Its water vapor transmission rate (WVTR) is 5.1 × 10 -3 g m -2 d -1 at 45 °C and 65% relative humidity (RH). The activation energy of permeability with the PDMS/AlO  x  film for moisture permeation is determined to be 35.5 kJ mol -1 . To investigate the moisture barrier capability of the PDMS/AlO  x  layer, (FAPbI 3 ) 0.85 (MAPbBr 3 ) 0.15 /spiro-OMeTAD/Au perovskite solar cells are fabricated, and encapsulated by the PDMS/AlO  x  film. To minimize the thermal damage to solar cells during ALD, AlO  x  deposition is performed at 95 °C. The solar cells exposed to 45 °C-65% RH for 300 h demonstrate less than a 5% drop in the power-conversion efficiency.
