Semitransparent OPV modules pass environmental chamber test requirements

Semitransparent OPV modules fabricated at Konarka production facility and laminated between two pieces of flexible barrier films and glass sheets meet IEC-61646 environmental chamber tests as required for thin film based photovoltaic modules. These flexible and rigid OPV modules respectively demonstrated less than 4% and 8% efficiency changes after damp heat, thermal cycling and a sequence test. For the first time, these tests confirm that OPV laminated in flexible barriers or between rigid glass sheets can withstand critical IEC stress test. Third party evaluations were performed by TÜV Rheinland in its Solar Energy Assessment Center in Cologne, Germany.
