Dye solar cells (DSC) are expected to have a great application potential for integration into buildings (BIPV) and facades (BAPV), due to their semi-transparent properties. Since the introduction of DSCs in 1991 by O´Regan and Grätzel [1] there has been intensive research and development of dye solar cells and the first companies have launched commercially available modules. In this project we have studied modules from the two companies, Glass2energy and Solaronix, both from Schwitzerland, in order to assess their transparency and light to electricity efficiency under Danish sunlight conditions. The two 50*35 cm modules from Solaronix are prepared with the ruthenium dyes Black Dye and N719 respectively, and the two small 12*12 cm Glass2energy test modules contain the ruthenium dye C101. The experimental study was performed 26/11-2013 at Roskilde University, on a clear sunny day with an estimated light intensity of 450 W/m2 on a vertical surface. The modules were mounted on a vertical southfacing glass façade. The same two Glass2energy modules were also measured at DTU Energy Conversion, Risø under standard solar cell testing conditions (1000 W/m2), in order to compare the two sets of performance data. With the sun as lightsource we obtained efficiencies of the red N719 Solaronix Module to be 0.7-0.8 % based on the active dye area, which is approximately 2 times less than obtained by Solaronix. For the Glass2energy an average active area efficiency of 1.6% was obtained, whereas the measurement at 1000W/m2 gave 2.1-2.3%. Based on our own measured efficiency data an expected electricity production of a 30 m2 south-facing vertical surface of Solaronix modules mounted in Denmark is 150-200 kWh/yr from a 30 m2 south-facing vertical surface of Solaronix modules mounted in Denmark is expected. The transparency of the modules where found to be 30-50 % of the total sunlight irradiation and 14-22 % obtained with a LUX meter.
