Abstract


Dielectric mirrors are wavelength-selective mirrors which are based on thin

film interference effects. Their optical band can precisely be adjusted in

width, position, and reflectance by the refractive index of the applied materials,

the layers’ thicknesses, and the amount of deposited layers. Nowadays,

they are a well-known light management tool for efficiency enhancement in,

for example, semitransparent organic solar cells (OSCs) and light guiding

in organic light-emitting diodes (OLEDs). However, most of the dielectric

mirrors are still fabricated by lab-scale techniques such as spin-coating or

physical vapor deposition under vacuum. Large-scale, fully printed (maximum

20 × 20 cm2) dielectric mirrors with adjustable reflectance characteristics are

fabricated, using temperatures of maximum 50 °C and alcohol-based inks.

According to the moderate processing conditions they can be easily deposited

not only on rigid glass substrates but also on flexible foils. They show

high stability against humidity, light irradiation, and temperature, positioning

themselves as good candidates for applications in OLEDs and OSCs. Eventually,

by simulations and experiments it is verified that a moderate degree of variations in layer thickness and surface roughness can suppress side interference

fringes, while not impacting the main transmittance minimum or the

main reflection maximum, respectively.
