摘要
Indium-free transparent and highly conductive multilayer AZO/Ag/AZO structures were grown by RF sputtering at room temperature on glass substrates varying the Ag film thickness from 2 to 15 nm. The AZO/Ag/AZO electrodes exhibited superior sheet resistance and optical properties compared to optimized AZO film. The best multilayer has a sheet resistance of 5.7 Omega/sq and average transmittance is about 75% in the visible light region. In order to evaluate the multilayer as TCO, we compared the Haacke figure of merit at a fixed wavelength and the one that considers the photonic flux density, for a CdTe and organic P3HT:PCBM absorber layer in solar cells. The best Haacke figure of merit value was 5.7 x 10(-2) Omega(-1) for 9 nm of Ag thickness, higher than those found up to now. Our indium-free multilayer deposited at room temperature has promising optoelectronic properties for flexible devices. (C) 2018 Elsevier Ltd. All rights reserved.
