Effects of Backbone Planarity and Tightly Packed Alkyl Chains in the D-A Polymers for OPVs |
| 초록 |
The photostability of D−A polymers remains a critical issue despite recent improvements in the PCEs of OPV cells. We report the synthesis of three highly photostable polymers (PDTBDT-BZ, PDTBDTBZF, and PDTBDT-BZF2) and their suitability for use in high-performance OPV cells. We ascribed the high photostability of the polymers to both the intrinsically photostable chemical moieties and the dense packing of alkyl side chains and planar backbone polymer chains, which prevents oxygen diffusion into the PDTBDT-BZ films. This work demonstrates the high photostability of planar PDTBDT-BZ series polymers composed of photostable DTBDT and BZ moieties and suggests a design rule to synthesize highly photostable photovoltaic materials. |
