Polymer solar cell modules based on the standard polymer-fullerene system of to-date, P3HT-PCBM, have been prepared and characterized. We have observed only a loss of ca. 20% when up scaling the active area of the solar cell by a factor somewhat larger than 10. A solar cell efficiency of 3% and a module efficiency of 1.9%, relating to the total area, are reported. The route for further optimization of module performance is discussed based on analysing the existing loss factors within this material system. We made thermographic measurements on the modules and identified parasitic shunts.
