Transparente Elektroden aus Silber

Transparent electrodes made of silver Thin coatings of silver are used in heat control windows. They have a high conductivity and a high transmittance, especially in the visible range of the spectrum. The transmittance decreases in the near infrared, which can be compensated by gains due to an efficient utilisation of interferences. Silver coatings can be produced at low cost. Especially, it is possible to deposit them also on flexible foils. By additional dielectric layers, further demands can be fulfilled, without an impairment of the conductivity. Examples are the prevention of barriers, the adjustment of the work function or the stabilisation against subsequent processes. By this, silver electrodes are of specific interest for organic light emitting diodes or solar cells.
