“…ITO material is defined as conducting material with resistivity value of 540 μohm‐cm, and the absorption data are obtained from 33 . The possibility of creating CZTS/ITO and ITO/AZO interfaces is experimentally realized in References 34 and 35, and the proposed tandem structure shown in Figure 2A can be experimentally fabricated. The tandem structure is illuminated with AM 1.5 radiation with intensity of 100 mW/cm 2 .…”

Summary A dual‐junction Cu2ZnSnS4–Silicon (CZTS–Si)‐based tandem configuration is modeled and analyzed for its viability as a solar cell. The top and bottom modules in the tandem structure are validated by comparison with experiment. Initially, the designed tandem structure yields very low efficiency of 3.18%, and the various loss mechanisms are identified and investigated. The current mismatch between top and bottom cells and parasitic absorption (photon losses) are suggested to be the major causes limiting the short circuit current and hence the efficiency of the device. We optimize the material parameters within experimentally achievable limits in order to obtain current matching, and the optimized thicknesses of copper zinc tin sulfide (CZTS) and silicon (Si) absorbers are found to be 150 nm and 250 μm, respectively. The simulation results revealed that the photon losses are reduced, and overall absorption in the longer wavelength region has enhanced with the replacement of cadmium sulfide (CdS) by zinc sulfide (ZnS) buffer and careful optimization of the front layers of the device. The maximum predicted efficiency of tandem structure is >20% by minimizing the recombination centers within the experimentally obtainable ranges and improving the carrier separation process.

“…For example, static charges oen bring about the electrostatic adhesion of dust, and discharging may lead to breakdown of electronic components, and in some situations can even cause combustion or an explosion. [1][2][3] To solve the issue of charge accumulation, some conductive materials, such as 2-D layered MXENE, 4 conductive polymers, 5-10 conductive oxides, [11][12][13][14][15][16] carbon materials, [17][18][19] and metal nanowires, [20][21][22][23][24][25][26][27][28] are adopted as the antistatic materials to be coated on the surface of some insulating materials. Among these materials, the conductive polymers have relatively poor conductivity and stability, thus they are not suitable for actual applications especially in harsh space environmental conditions.…”

“…In particular, the properties of transparent flexible electrodes are very important in optoelectronics because these support all functional layers as a substrate [4,5]. Indium tin oxide (ITO) deposited on a flexible film was a popular material for flexible transparent electrodes because of its high conductivity and stability as an electrode and because of being common in rigid electronics [6][7][8][9][10]. However, it cracks easily when stress is applied and is not suitable for flexible electronic devices that have to be bent repeatedly [11][12][13].…”

Thickness Uniformity Dependence on Polymer Viscosity in Silver-Nanowire-Embedded Flexible and Transparent Electrodes

We herein report the effect of the viscosity of a prepolymer solution on the thickness uniformity of silver-nanowire-embedded flexible transparent electrodes. We adopted a model system with all the prepolymer solutions possessing identical physical properties except for the viscosity and then explored the most common prepolymer solutions for silver-nanowire-embedded flexible electrodes. In all experiments, single-step spin coating was conducted to coat the prepolymer solution on silver nanowires. We found that the electrodes were thinner for lower viscosity. However, the thickness ratio between the center and edge was comparable (50–60%) and independent of the prepolymer solution viscosity. This indicates that the viscosity does not determine the thickness uniformity, and that the coating method itself is vital to obtain films with uniform thickness. The flexible electrodes were introduced into organic solar cells. Their device performance was comparable regardless of the position of the electrodes and their thickness. This is because the thickness difference of the flexible electrodes did not affect their transmittance significantly. Thus, we conclude that although different coating approaches are needed to obtain flexible electrodes with high uniformity, the performance of optoelectronic devices on silver-nanowire-embedded flexible electrodes is independent of them.
