The utilization of donor materials with complex structures obviously increases the costs of organic photovoltaic (OPV) cells. Therefore, low-cost and high-performance are two issues that must be considered when designing polymer donors for the preparations of large-area OPV cells. Here, a poly(thienylene vinylene) derivative, named PTVT-BT was reported. PTVT-BT has a very simple completely non-fused molecular structure. PTVT-BT shows planar molecular structure and obvious solution aggregation effect. Besides, PTVT-BT demonstrates a high hole mobility up to the magnitude of 10^-2 cm^-2 V^-1 s^-1. The external quantum efficiency of electroluminescence of PTVT-BT is 7 × 10^-3. As a result, the OPV cell based on PTVT-BT:eC9 demonstrates a power conversion efficiency (PCE) of 16.31%, which is the highest value among the poly(thienylene vinylene)- and polythiophene-based OPV cells. The tandem OPV cell with PTVT-BT as the donor of the sub-cell yields an outstanding PCE of 18.49%. Besides, the indoor OPV cell based on PTVT-BT:BTA3 exhibits a PCE of 27.30% under a light-emitting diode (LED) illumination of 1000 lux (2700 K). This study indicates that PTV-derivative is a kind of promising material for the future OPV industrialization.

使用具有复杂结构的供体材料明显增加了有机光伏（OPV）电池的成本。因此，低成本和高性能是设计用于制备大面积OPV电池的聚合物供体时必须考虑的两个问题。在这里，报道了一种名为 PTVT-BT 的聚（亚噻吩基亚乙烯基）衍生物。PTVT-BT 具有非常简单的完全非稠合分子结构。PTVT-BT呈现平面分子结构和明显的溶液聚集效应。^{此外，PTVT-BT表现出高达10 -2} cm ^-2 V ^-1 s ^-1量级的高空穴迁移率。PTVT-BT的电致发光外量子效率为7×10 ^-3. 结果，基于 PTVT-BT:eC9 的 OPV 电池的功率转换效率 (PCE) 为 16.31%，是聚 (噻吩乙烯) 和聚噻吩基 OPV 电池中的最高值。以 PTVT-BT 作为子电池供体的串联 OPV 电池产生了 18.49% 的出色 PCE。此外，基于 PTVT-BT:BTA3 的室内 OPV 电池在 1000 勒克斯 (2700 K) 的发光二极管 (LED) 照度下表现出 27.30% 的 PCE。该研究表明，PTV衍生物是一种很有前景的未来OPV产业化材料。
