“…31 For these reasons, many researchers have focused on bendable, ultrathin inorganic or inorganic/organic hybrid encapsulation layers with excellent gas-barrier properties. [32][33][34][35] However, physicochemically active species (such as plasma, chemical precursors, and solvents) and the high thermal energy produced by the deposition of the encapsulation layer can severely break down micro-and/or nano-scale semiconducting film morphologies, which leads to the deterioration of organic electronics. [18][19][20][36][37][38] Therefore, an ultrathin encapsulation layer, able to protect organic semiconducting layers from environmental damage, is still required.…”

“…A multi-layer barrier approach can be an effective solution. 42,271 Fahlteich et al reported two layers of metal oxide, e.g. aluminum oxide or zinc-tin oxide, 272 separated by a hybrid polymeric layer, 42 and deposited by sputtering and magnetron-PECVD.…”

Flexible Dye Solar Cells (FDSCs), in their most widespread architecture, are assembled with two opposing planar films or foil substrates in metal–plastic or plastic–plastic combinations. The use of one metal electrode enables the convenient utilization of materials and high temperature processes but is accompanied by issues including partial opacity of the electrolyte and catalyst layer. Constraints on the stability of plastic substrates have led to the development of a variety of alternative material formulations and processes to guarantee performance even at low temperatures compatible with plastic films. Recently, efforts in doing without transparent conducting oxides have led to the development of new unconventional architectures. Review of the operation of DSCs shows that initial target markets are represented by indoor applications where power output densities have been shown to outperform competing flexible photovoltaic technologies. Whereas performance, stability in particular, needs to be significantly improved for the adoption in long term outdoor installations, commercial products integrating FDCSs for indoor or portable use have already been launched. Issues pertaining progress in materials, processes, devices and industrialization of FDSCs will be analyzed and discussed in this review

A hybrid nanolaminates consisting of Al2O3/ZrO2/alucone (aluminum alkoxides with carbon-containing backbones) grown by atomic layer deposition (ALD) were reported for an encapsulation of organic light-emitting diodes (OLEDs). The electrical Ca test in this study was designed to measure the water vapor transmission rate (WVTR) of nanolaminates. We found that moisture barrier performance was improved with the increasing of the number of dyads (Al2O3/ZrO2/alucone) and the WVTR reached 8.5 × 10−5 g/m2/day at 25°C, relative humidity (RH) 85%. The half lifetime of a green OLED with the initial luminance of 1,500 cd/m2 reached 350 h using three pairs of the Al2O3 (15 nm)/ZrO2 (15 nm)/alucone (80 nm) as encapsulation layers.Electronic supplementary materialThe online version of this article (doi:10.1186/s11671-015-0857-8) contains supplementary material, which is available to authorized users.
