Highly Efficient Non-Fullerene based Organic Solar Cells with Improved Charge Transfer and Transport using the Post-Additive Soaking |
| 초록 |
An improved efficiency of non-fullerene acceptor-based organic solar cells based on PBDB-T : ITIC-m composites has been obtained by using post-additive soaking (PAS) treatments on pristine BHJ films. The PAS-treated BHJ films show improved carrier dynamics in charge transfer and transport, leading to increased photocurrent and fill factors in the photovoltaic devices, followed by a high power conversion efficiency of 12.3%, which is an increase of 28% compared to that of the control device. We found that this superior performance predominantly resulted from improved exciton dissociation and enhanced electron transport after photoexcitation of the ITIC-m phase. |
