Abstract:
 

Flexible permeation barriers are a key component for flexible organic light emitting diodes and organic solar cells. Roll-toroll processing is a solution to reduce the costs for barriers. However, usual web handling includes roll-layer contact. This physical contact may be critical for high quality barriers, because the barrier performance deteriorates drastically with the introduction of only a few defects. In this work, it is demonstrated that avoiding roll-barrier contact improves the barrier performance by at least a factor of 5. To minimize barrier defects caused by substrate surface irregularities, a high quality substrate was used for this study. Due to the high substrate quality, a water vapor transmission rate (WVTR) of 0.001 g/(m²d) was measured for a 37 nm thick single layer of sputtered zinc tin oxide (ZTO).
