摘要

In this paper we report on the outcome of a German network project with 10 partners from universitiesand institutes on dye solar cells (DSC). In addition, we give an overview in the field and evaluate the concept ofmonolithic DSC further with respect to upscaling and producibility on glass substrates. We have developed amanufacturing process for monolithic DSC modules which is based entirely on screen printing. Similar to ourprevious experience gained in sealing of standard DSC, the encapsulation of the modules can be achieved in a fusingstep by soldering of glass frit layers. A platinum free, conductive counter electrode layer, showing a charge transferresistance of R_(CT) < 1.5 Ohm/cm~2, has been realised by firing a graphite / carbon black composite under inertatmosphere. A certain patterning of the porous counter electrode layer is applied in order to achieve a fast andhomogenous coloration of monolithic DSC modules by injecting a highly concentrated dye solution. Various types ofnon-volatile imidazolium based ionic liquid electrolytes have been synthesised and optimised for their diffusionlimited currents and charge recombination in DSC.
