Efficient Perovskite Solar Cells based on New Hole Transporting Conjugated Polymer and a Novel Method for Hole Mobility Measurement: TMS |
| 초록 |
Recent developments in light absorber materials based on perovskite have yielded PCE exceeding 15% in hybrid solar cells. In this work, hybrid solar cells based on a CH3NH3PbI3 perovskite and a diketopyrrolopyrrole based hole transport polymer was successfully prepared. The excellent optical and electrical properties of perovskite used as a light harvester yielded a 9.2% PCE for the best-performing cell. The high PCE was attributed to the optimal oxidation potential (5.4 eV) and excellent charge carrier mobility of the polymer. The long-term stability of the PDPPDBTE devices, as measured over 1000 hours under a humid atmosphere, guarantees the practical applicability of these solid-state hybrid solar cells under outdoor working condition due to its hydrophobic condition. These results suggest a broad strategy for developing efficient organic semiconductors, and further enhancements may potentially be realized by carefully tuning the energetic distributions of the HTP and perovskite. |
