The power conversion efficiency (PCE) of polymer-based photovoltaic devices is largely affected by light absorption property and charge mobility of active layers as well as energy difference between the HOMO of p-type material and LUMO of n-type material. Thus in order to increase the PCE of organic solar cells, new p-type materials should be developed such that their absorption ranges are wide enough along with high molar absorptivity. A naphthalene derivative can be employed as an electron-donating monomer with a good hole transporting property. On the other hand, an isoindigo derivative (II) can be used as a symmetrically planner electron-accepting monomer, which may result in strong π-π interactions and strong electron-withdrawing effects. In this study, a new p-type naphthalene-II polymer was synthesized. The performance of the polymer-based solar cells as well as basic characterizations will be presented in detail. |
