“…Furthermore there is less Cu accumulation at the surface of the electrode which leads to more performing OPVs. Unfortunately, here also the stability of the sheet resistance is not as high as that of structures using Ag as metal [25] (Figure 2). To try to understand this behaviour we had performed XPS studies to examine the profile of the multilayer structures.…”

“…The migration of Ag would predominantly take place along grain boundaries in the film, which are more pronounced for the rougher electrodes on PET. Moreover, when the samples are exposed to ambient conditions, humidity causes electrochemical reactions that produce Ag ions, fostering further diffusion on the surface, as has been observed for aged, evaporated MoO x /Ag/MoO x electrodes [49]. To test the hypothesis of the effect of the reactive plasma on the diffusion of Ag to the surface, DMD electrodes were also fabricated with the same layer thicknesses but with the MoO x layers deposited non-reactively.…”

Dielectric/metal/dielectric (DMD) transparent electrodes emerged as a compelling alternative to the widely used indium-tin-oxide (ITO) for solar cells and optoelectronic devices. DMD electrodes are especially attractive for flexible substrates, as, in contrast to ITO, they retain their low electrical resistance upon substrate bending and they do not require deposition at elevated temperatures. In a DMD, the choice of the dielectric is mainly dictated by the device architecture. Owing to its high work function, MoO 3 is a commonly used hole-selective dielectric layer. The present work investigates MoO x /metal/MoO x (with 2 \ x \ 3) DMD electrodes, with Ag and Au as metals, fabricated by direct current, magnetron sputtering, at industry-relevant, high deposition rates. This was possible with a properly engineered MoO x target, providing high electrical conductivity and compactness. The sputtered electrodes on polyethylene terephthalate (PET) substrates show higher figure-of-merit than similar, evaporated electrodes in the literature. It is shown that the DMD electrodes with amorphous MoO x layers have low stability in water, but they are stable to other solvents, such as toluene, dimethylsulfoxide (DMSO), dimethylformamide (DMF), chlorobenzene or chloroform, allowing their implementation in devices like organic light-emitting diodes or perovskite solar cells. Further, it is shown that the electrodes show dramatically enhanced mechanical stability compared to ITO, when subjected to tensile bending tests.

Paper is a flexible material, commonly used for information storage, writing, packaging or specialized purposes. It also has strong appeal as a substrate in the field of flexible printed electronics. Many applications, including safety, merchandising, smart labels/packing, chemical/biomedical sensors, require an energy source to power operation. Here we review progress regarding development of photovoltaic and energy storage devices on cellulosic substrates where one or more of the main material layers are deposited via solution processing or printing. Paper can be used simply as the flexible substrate or, exploiting its porous fibrelike nature, as an active film by infiltration or co-preparation with electronic materials. Solar cells with efficiencies of up to  4% on opaque and 9% on transparent substrates have been demonstrated. Recent developments in paper-based supercapacitors and batteries are also reviewed with maximum achieved capacity of 1350 mF cm -2 and 2000 mAh g -1 respectively.Analysing the literature, it becomes apparent that more work needs to be carried out in continuing to improve peak performance, but especially stability and the application of printing techniques, even roll-to-roll, over large areas. Paper is not only environmentally friendly and recyclable, it is thin, flexible, low-weight, biocompatible, and low-cost.
