Preparation and application of isoindigo derivative conjugated polymer introduced with heavy atom selenium |
| abstract |
The invention discloses the preparation and application of a conjugated polymer of isoindigo derivatives introduced with heavy atom selenium; the conjugated polymer is shown in formula (I): R is a C8～C20 alkyl chain, 1000≥n﹥1. The present invention introduces the heavy atom selenium atom into hemi-isoindigo for the first time, and synthesizes a new type of monomer. The influence of the introduction of heavy atoms on the photovoltaic performance of the polymer is revealed. The synthesis steps of the polymer are simple, the yield is high, and it shows good ultraviolet spectrum absorption. The introduction of heavy atoms will reduce the molar extinction coefficient of the polymer and red-shift the absorption spectrum. The two conjugated polymers prepared by the invention can be used as donor materials in the organic semiconductor layer and applied in polymer solar cell tests. The photoelectric conversion efficiencies of 4.28% and 3.36% were respectively obtained in the tests of organic thin film solar cells with the structure ITO/ZnO/polymer:PC 61 BM/MoO 3 /Ag. |
