The article by Jung-Yong Lee, Stephen T. Connor, Yi Cui, and Peter Peumans presents a novel solution-processed transparent electrode made of random meshes of metal nanowires. These electrodes exhibit optical transparency comparable to or better than that of metal-oxide thin films for the same sheet resistance. The researchers demonstrate that subwavelength periodic metal gratings have superior optical transmission and sheet resistance compared to indium tin oxide (ITO). They then show that random meshes of metal nanowires processed from solution achieve similar performance to these gratings. The Ag nanowire mesh electrodes show a solar photon flux-weighted transmissivity of up to 85% at a sheet resistance of 10Ω/sq and can be bent to a radius of 4 mm without affecting the sheet resistance. Organic photovoltaic cells deposited on these electrodes exhibit improved photocurrents compared to those on ITO-coated substrates. The low-cost fabrication method, compatibility with flexible substrates, and enhanced performance make these metal nanowire mesh electrodes attractive for various applications, including organic solar cells.The article by Jung-Yong Lee, Stephen T.
