        Abstract:
        This study addresses the issue of poor intercomparability of measurements of organic photovoltaic OPV)devices among different laboratories. We  present a round robin performance testing of  novel OPV devices among 16 laboratories, organized within the framework of European Research Infrastructure Project (SOPHIA) and European Energy Research  Alliance (EERA). Three types of OPVs  with different structures, dimensions and encapsulations are studied  and compared with reference Si  solar  cells certi?ed by  accredited laboratories. The  agreement of the measurements of these among different lab- oratories is  analyzed by  focusing on   testing  procedures, testing equipment and sample designs. A number of deviations and pitfalls are revealed and based on the analyses, a set of recommendations are suggested for improving the agreement among the measurements of such OPV technologies.
