The polymer solar cell efficiency over 10% based on siloxane-terminated side-chain polymer donor |
| 초록 |
Halogenation atoms have been widely used into organic semiconductor materials to improve the photovoltaic device performance of polymer solar cells (PSCs). A novel wide-bandgap conjugated polymers (P1 and P2) was designed and synthesized which consists of BDT as donor and BDD as acceptor unit. Herein, chlorine and siloxane-terminated side chains are important strategies to enhance the absorption coefficient, solubility, dominated the energy losses and increasing the mobility of photoactive materials. Non-halogenated solvent processed for P2 polymer with IT-4F acceptor achieved the PCE of 10.52% [(Voc) of 0.85 V, (Jsc) of 17.50 mA/cm2, and (FF) of 70.78%] with effective surface modification treatment on ZnO layer. Whereas, the P1 polymer obtained PCE of 8.42%. Overall, the siloxane-terminated side chain with Cl designed polymer dedicated to device via effective surface modified treatment on ZnO layer yielded high performance of PSCs. |
