Hybrid electron-collecting buffer layers with nanocrater morphology for high efficiency polymer:nonfullerene solar cells |
| 초록 |
Charge-collecting buffer layers, which are known to play a crucial role in promoting effective charge transfer actions in organic solar cells (OSCs), have been intensively studied for the last two decades. Recently, the power conversion efficiency (PCE) of inverted-type OSCs has exceeded 12~14% even though their stability improvement is still on-going. These high efficiency inverted OSCs composed of metal oxide-based charge-collecting buffer layers which need high temperature processes and have inherently different surface energies compared to organic materials used for the bulk heterojunction layers (BHJs) in inverted OSCs. These drawbacks result in limitations of using flexible plastic film substrates and poor stability of devices. This presentation demonstrates brand-new approaches to make organic/inorganic hybrid charge-collecting buffer layers, which can be processed at low temperatures, with a peculiar nanocrater morphology leading to enhanced adhesion with the BHJ layers. |
