Dye solar modules for facade applications. Recent results from project ColorSol

With respect to a first market introduction, one advantage of dye solar cell (DSC) modules is the combination of photovoltaic (PV) solar electricity with decorative aspects. We report on the recent results achieved in the frame of the German project ColorSol. The project focuses on the application field of building-integrated PVs (facades, PV-glazing, etc.). Design concepts, as well as scenarios for the application of the DSC technology in architecture and facade planning are developed and the application potential is quantified in cooperation with potential users. Prototypes of glass facade elements (70 cm x 200 cm) have been developed which consist of several serially interconnected DSC modules each with a size of 30 cm x 30 cm. The results of module characteristics under various outdoor illumination conditions and under partial shading are reported. Visual impressions of the DSC facade elements are presented.
