Description

technical field [0001] The invention belongs to the field of transparent conductive films, in particular to a particle-free silver ink and a preparation method thereof, a transparent silver conductive film and a preparation method thereof. Background technique [0002] Transparent conductive film is a class of high conductivity (<10 -3 Ω cm), visible light range (λ = 380 ~ 780nm) has high light transmittance (T avg >80%), films with high reflectivity in the range of infrared light (>760nm), currently mainly include metal film system, oxide film system, etc. Transparency requires that the bandgap width of the material is greater than 3.1eV of the energy of visible light photons, and the concentration of free carriers is as small as possible; while conduction means that the free carrier concentration in the material is large enough, and the greater the free carrier concentration, the material The worse the light transmittance, so transparency and conductivity are th...
