Abstract

Layers of ITO nanoparticles were deposited on soda-lime substrates by spincoating in order to produce conductive transparent electrodes. Different lasers in the UV and mid infrared wavelength region were used for post deposition treatment of the layers to remove stabilizing agents contained in the layers to enhance particle-particle contact and significantly increase conductivities. Irradiation with lasers in the infrared region showed good results in terms of stabilizer removal without undesired oxidizing effects to the particle layer. Conductivities of up to 120 S/cm were achieved, which is comparable to layer treatment by annealing and a subsequent chemical reducing step.
