“…Not only the MoO 3 /Ag/MoO 3 structure resist perfectly to this adhesion test since the film is not at all removed, but the sheet resistance of these structures did not increase after the test. We have also measured more precisely the mechanical properties and the adhesion of the MoO 3 /Ag/MoO 3 structure to the substrates [46]. Using a scratching test apparartus, we have shown that, if the MoO 3 /Ag/MoO 3 structures exhibit a good adhesion to the substrates, this adhesion is not as high as that of ITO.…”

“…From table 1, the optimum structure is obtained with 12 nm of silver. For comparison the figure of merit of ITO used in the laboratry is 15.4x10 -3 Ω -1 when deposited on glass and 5.4x10 -3 Ω -1 when deposited onto PET [56]. It can be concluded that optimum compromise between optical and electrical properties of the D/Ag/D structures is similar to that of ITO.…”

“…The AFM image processing was done using the Gwyddion V2.36 program which allows, calculation of the roughness of the surface (RMS). The scotch tape method [46] was used to estimate the adhesion of the structures to the substrate. This test is only qualitative but it allows screening films involving poor adhesion from those where adhesion is good.…”

The present manuscript is dedicated to In free transparent conductive andflexible heterostructure electrodes. The new electrodes correspond todielectric/metal/dielectic (D/M/D) multilayer structures deposited under vacuum. In thepresent work, after a fast review of the general properties of D/M/D electrodes using Ag asmetal, we then develop the study of D/Cu/D multilayer structures. We propose to substituteCu to Ag, because it is far cheaper. However, Cu having tendency to diffuse into manydielectrics it is difficult to obtain stable electrodes. We show that using Cu:alloys, i.e. Cu:Niand Cu:Al, as metal it is possible to decrease significantly the Cu ions diffusion and toincrease significantly the stability of the multilayer electrodes with Cu. Finally, we show thatwhen these electrodes are used as anode in organic photovoltaic cells, they can allowachieving efficiency similar to that obtained with ITO.

“…Recently, TCEs (Transparent Conductive Electrodes) have been capturing substantial attention for various applications including solar cells, flat panel displays, optical sensors, touch screen panels and organic light emitting diodes (OLEDs) (Guillén and Herrero, 2011;Wang et al, 2019;Hssein et al, 2017;Kim and Yer, 2016). Many kinds of wide band-gap materials such as ZnO; AZO, ITO, TiO 2 and SnO 2 have confirmed their usefulness as basic building blocks for TCE applications, thanks to their fascinating optical and electrical properties (Kim and Yer, 2016;Liu et al, 2015;Seeger et al, 2016;Miao et al, 2014).…”

“…To enhance the transmittance and at the same time obtain an effective mirror-like thin metal film [29,30], the uniformity, thickness, reflective and transparent properties of the metal film must be controlled carefully [31]. The combination of metal/dielectric could be an effective structure to adjust the optical properties of thin metal film [32].…”

Optical microcavity configuration is one optical strategy to enhance light trapping in devices using planar electrodes. In this work, the potential application of optical microcavity configuration with ultrathin metal electrodes in highly efficient perovskite solar cells (PSCs) was investigated. By comparing with the device with conventional indium-tin-oxide (ITO) electrodes, it is shown that by carefully designing the Ag/dielectric planar electrode, a device with an optical microcavity structure can achieve comparable—or even higher—power conversion efficiency than a conventional device. Moreover, there is a relative high tolerance for the Ag film thickness in the optical microcavity structure. When the thickness of the Ag film is increased from 8 to 12 nm, the device still can attain the performance level of a conventional device. This gives a process tolerance to fabricate devices with an optical microcavity structure and reduces process difficulty. This work indicates the great application potential of optical microcavities with ultrathin metal electrodes in PSCs; more research attention should be paid in this field.
