Impact of 3D Morphology on the Photovoltaic Property of All-Polymer Solar Cells Processed by Non-halogenated Solvents |
| 초록 |
Organic solar cells using halogenated solvents recorded high efficiencies over 10%. However, halogenated solvents are very toxic to human health and environment. These solvents must be replaced with environmentally friendly non-chlorinated solvents. In these regards, we have investigated all-polymer solar cells employing PTB7-Th and PNDI2OD-T2 polymers to find the dependence of photovoltaic properties on the processing solvent. We find that toluene and xylene are better processing solvents than halogenated solvents for the photovoltaic performance of PTB7-Th:PNDI2OD-T2 based devices. 3D TEM demonstrated that more ideal blend morphology in toluene and xylene-used active layer films was responsible for the solvent-property relationship. |
