ITO films with a sheet resistance of R<sub>s</sub> = 10 Ω/sq and a T = 90% transmittance, we turn to materials that can be serious alternatives for ITO, such as graphene T = 97% for R<sub>s</sub> = 60 Ω/sq and the micro-mesh metal. Wire mesh seems to be the best alternative T = 93% for R<sub>s</sub> R<sub>s</sub> = 0.022 Ω/sq at T = 81%, this is the micrometric pitch mesh.展开更多
