In this work, a non-fullerene acceptor molecule (ITIC-FOR) based on heptacyclic (indacenodithieno[3,2-b]thiophene) IDTT as the core with F-phenylalkoxy (FOR) as a sidechain was designed and synthesized. The photovoltaicproperties of the HFQx-T:ITIC-FOR based non-fullerene polymer solar cells (NF-PSCs) were explored. By device optimization, a good power conversion efficiency (PCE) of 7.33% was obtained

We report a new smallmolecularacceptor, ITIC‐OEG, which is based on indacenodithieno[3,2‐b]thiophene and 1,1‐(dicyanomethylene)‐3‐ indanone including oligoethyleneglycol (OEG) side‐chains. ITIC‐OEG was found to have higher dielectric constant (εr=5.6) than that of a reference molecule of ITIC with normal alkyl substituents (εr=3.9). The dielectric constant of medium influences significantly the exciton
我们报告了一种新的小分子受体ITIC-OEG,它基于indacenodithieno [3,2- b ]噻吩和1,1-(二氰基亚甲基)-3-茚满酮(包括低聚乙二醇(OEG)侧链)。ITIC-OEG被发现具有较高的介电常数(ε - [R = 5.6)比ITIC的与正常的烷基取代基的参照分子(ε ř= 3.9)。介质的介电常数会显着影响激子结合能以及由此产生的电荷分离和重组。通过与ITIC-OEG的半结晶供体聚合物PPDT2FBT共混,研究了ITIC-OEG的光学,电化学和形态学特性及其光伏特性。ITIC-OEG比ITIC显示出更多的红移吸收和更强的晶体堆积。但是,与PPDT2FBT:ITIC(5.52%PCE)相比,PPDT2FBT:ITIC-OEG的光伏性能较低(功率转换效率为1.58%,PCE)。PPDT2FBT与ITIC-OEG之间的不相容性(由于OEG链的高度亲水性)导致混合不良,并且在300

donor with two thieno[3,2‐b]thiophenes. The polymer derived from this donor possesses longer effective conjugation and better planarity, which improves electron delocalization along the polymer backbone and charge mobility. The polymersolarcell device using PIDTT‐DFBT shows a high power conversion efficiency of 7.03% with a large open‐circuit voltage of 0.95 V without using any additives or post‐solvent/thermal
