We present the results of a study of flat and uniform poly(3-hexylthiophene):methanofullerene bulk-heterojunction photovoltaic (PV) layers that were produced by a simple pre-metered horizontal-dipping process for the fabrication of polymer solar cells (PSCs). It is shown that this process can produce high quality and thin films by utilizing the downstream meniscus of the solution, which can be controlled by adjusting experimental parameters of the gap height and the carrying speed. It is also shown that the produced PV film exhibits high power conversion efficiency of ca. 4.2% with a large active area. It was demonstrated that this pre-metered process for solution coating may be promising for achieving highly efficient, reliable, and large-area PSCs.
我们展示了一项关于平整且均匀的聚（3-己基噻吩）：甲醇富勒烯本体异质结光伏（PV）层的研究结果，这些PV层是通过一种简单的预计量水平浸渍工艺制备聚合物太阳能电池（PSC）而得到的。结果表明，该工艺通过利用溶液的下游弯月面能够制备出高质量的薄膜，且可通过调整间隙高度和输送速度等实验参数来控制弯月面。研究还表明，所制备的PV薄膜在大面积时展现出约4.2%的高功率转换效率。结果证明，这种用于溶液涂层的预计量工艺对于实现高效、可靠且大面积的PSC可能具有前景。
