A round robin for the performance of roll-to-roll coated flexible large-area polymer solar-cell modules involving 18 different laboratories in Northern America, Europe and Middle East is presented. The study involved the performance measurement of the devices at one location (Risø DTU) followed by transportation to a participating laboratory for performance measurement and return to the starting location (Risø DTU) for re-measurement of the performance. It was found possible to package polymer solar-cell modules using a flexible plastic barrier material in such a manner that degradation of the devices played a relatively small role in the experiment that has taken place over 4 months. The method of transportation followed both air-mail and surface-mail paths.

    • ... processes based on all printing techniques have been employed to fabricate devices on flexible substrates with inverted cell geometry [3, 4] and with ITO-free fabrication steps [5, 6]. In addition, the relative stability towards degradation of encapsulated large area PCS has been demonstrated through round robin and interlaboratory studies on devices fabricated on flexible substrates using full roll-to-roll processing techniques [7]...

    • ...Assuming that the spectral differences play a minor role and using the temperature coefficients observed for the same device type using regioregular P3HT:PCBM as the active layer (+25 μA per degree and −5.7 mV per degree) [15], one can estimate a difference in the observed module current of about +1.5 mA and −350 mV in the module voltage between 17 and 78 ◦ C (see Fig. 6). These values agree quite well with the observed differences...
