Abstract

A zwitter-ionic polymer poly (sulfobetaine methacrylate) (denoted by PSBMA) was employed as an electron transportation layer (ETL) in polymer solar cells (PSCs) based on poly(3-hexylthiophene) (P3HT):[6,6]-phenyl-C-butyric acid methyl ester (PCBM). PSBMA is highly soluble in trifluoroethanol, showing an orthogonal solubility to the solvent of the active layer in the preparation of multilayered PSCs. Upon introduction of PSBMA, the short circuit current and as a consequence the power conversion efficiency of the corresponding PSCs are dramatically improved, which can be because of the relatively high polarity of PSBMA compared with the other ETLs. This study demonstrated that zwitter-ionic polymer should be a competitive potential candidate of ETLs in PSCs.

摘要

一种两性离子聚合物聚(甲基丙烯酸磺酸甜菜碱)(记为PSBMA)被用作基于聚(3-己基噻吩)(P3HT):[6,6]-苯基-C-丁酸甲酯(PCBM)的聚合物太阳能电池(PSC)中的电子传输层(ETL)。PSBMA在三氟乙醇中高度可溶,在制备多层PSC时,它与活性层的溶剂具有正交溶解性。引入PSBMA后,相应PSC的短路电流以及功率转换效率都得到了显著提高,这可能是因为与其他ETL相比,PSBMA具有相对较高的极性。这项研究表明,两性离子聚合物应该是PSC中ETL的一个有竞争力的潜在候选者。
