High efficiency inorganic/polymer hybrid solar cells with interfacial modifications |
| 초록 |
The inserting of an interfacial modifier between the inorganic and organic interface is an effective approach to improve electric characteristics and non-ideal interfacial contact in polymer/inorganic hybrid solar cells (HSCs). We synthesized different interfacial modifiers (IMs) with different functionality and energy levels following the “donor−acceptor” design concept. These IMs were used to modify the interfaces of ZnO and photoactive polymer in HSCs. The surface modification of ZnO with IMs exhibited enhanced solar cell performance when compared to the unmodified devices. These results demonstrate that modified ZnO with IMs has three most beneficial functions of reducing the number of defect sites and traps on the ZnO surface, facilitating the charge carriers by controlled work function of ZnO and increasing the compatibility of hydrophilic ZnO with the polymer layer. |
