Worldwide outdoor round robin study of organic photovoltaic devices and modules
article
Accurate characterization and reporting of organic photovoltaic (OPV) device performance remains oneof the important challenges in thefield. The large spread among the efficiencies of devices with the samestructure reported by different groups is significantly caused by different procedures and equipmentused during testing. The presented article addresses this issue by offering a new method of devicetesting using“suitcase sample”approach combined with outdoor testing that limits the diversity of theequipment, and a strict measurement protocol. A round robin outdoor characterization of roll-to-rollcoated OPV cells and modules conducted among 46 laboratories worldwide is presented, where thesamples and the testing equipment were integrated in a compact suitcase that served both as a sampletransportation tool and as a holder and test equipment during testing. In addition, an internet basedcoordination was used via plasticphotovoltaics.org that allowed fast and efficient communication amongparticipants and provided a controlled reporting format for the results that eased the analysis of thedata. The reported deviations among the laboratories were limited to 5% when compared to the Sireference device integrated in the suitcase and were up to 8% when calculated using the local irradiancedata. Therefore, this method offers a fast, cheap and efficient tool for sample sharing and testing thatallows conducting outdoor measurements of OPV devices in a reproducible manner.
