3Enhanced thermal stability of organic solar cells comprising ternary D-D-A bulk-heterojunctions显示文摘Ternary absorber blends have recently been identified as promising concepts to spectrally broaden the absorption of organic bulkheterojunction solar cells and hence to improve their power conversion efficiencies.In this work,we demonstrate that D-D-A ternary blends comprising two donor polymers and the acceptor PC61BM can also significantly enhance the thermal stability of the solar cell.Upon harsh thermal stress at 120°C for 2 h,the ternary solar cells show only a minor relative deterioration of 10%.Whereas the polymer/fullerene blend PTB7-Th:PC61BM is rather unstable under these conditions,its degradation was efficiently suppressed by incorporating the near infrared-absorbing polymer PDTP–DFBT.Spectroscopic ellipsometry investigations and an effective medium analysis of the ternary absorber blend revealed that the domain conformation in presence of PDTP–DFBT remains stable whereas the domain conformation changes in its absence.The ternary PTB7-Th:PDTP–DFBT:PC61BM solar cells yield thermally stable power conversion efficiencies of up to 6%.Dominik Landerer Adrian Mertens Dieter Freis Robert Droll Tobias Leonhard Alexander Deniz Schulz Daniel Bahro Alexander Colsmann 2017npj Flexible Electronics2017,1,1:0
