The research results were published in《Nano Energy》 in 2022.COA of Formula: C16H34O The article conveys some information:
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 mol. structure. PTVT-BT shows planar mol. 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 x 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 lx (2700 K). This study indicates that PTV-derivative is a kind of promising material for the future OPV industrialization. The experimental procedure involved many compounds, such as 2-Hexyl-1-decanol (cas: 2425-77-6) .
2-Hexyl-1-decanol(cas: 2425-77-6) is a branched alcohol. It is one of the constituent of the essential oil, extracted from the roots of Adiantum flabellulatum. COA of Formula: C16H34O
