Improvement of optical and electric characteristics of MoO3/Ag film/MoO3 flexible transparent electrode with metallic grid

Abstract

In this paper, the authors report rationally designed, innovative tri-layer flexible transparent conductive electrodes (TCEs) fabricated via thermal deposition. The proposed structure improves transparency compared with that of the traditional tri-layer electrode (dielectric/metal film/dielectric) by using metallic grid patterns (dielectric/metal grids/dielectric). The obtained MoO3/Ag grids/MoO3 TCEs show low sheet resistance and good mechanical properties. The sheet resistance of the proposed electrodes is 5.88 Ω/square and the transmittance reaches 76.5%, which are better than those of conventional MoO3/Ag film/MoO3 electrodes (6.12 Ω/square, <70%). The mechanical properties are significantly improved compared with those of MoO3/Ag film/MoO3 in the bending test under both tensile and compressive stress. The surface features of the MoO3/Ag grids/MoO3 TCEs were measured using the contact angle method to calculate the surface energy and polarity. The polarity is 0.5–0.26, which is better than those of indium tin oxide (0.35) and MoO3/Ag film/MoO3 (0.5–0.0058) electrodes for 0–800 bending cycles. The proposed flexible transparent electrodes show good optical, electrical, and mechanical characteristics and have potential for application in optoelectronics.

Photopically Transparent Organic Solar Cells with Tungsten Oxide-Based Multilayer Electrodes

“…Assuming the formation of identical Ag films based on similar sheet resistances, the lower APT of MoO 3 -based T-OSCs can be attributed to the higher light absorption of MoO 3 itself. Generally, the LUE (LUE; PCE × APT) is used to fairly compare various types of T-OSCs because of the trade-off relationship between the PCE and APT. , The LUE values of the devices, WO 3 -based T-OSCs and MoO 3 -based T-OSCs, are 3.27 and 2.86%, respectively, as shown in Table , denoting that WO 3 -based T-OSCs are better T-OSCs than MoO 3 -based T-OSCs. Referring to the APT-dependent LUE of the full device configuration, our work recorded the highest LUE (3.27%) and notable transparency (46.7%) of the device.…”
