在这项研究中，我们提出了使用的共混物，包括聚（3，4-乙撑二氧噻吩）：聚苯乙烯磺酸盐（PEDOT：PSS）和聚乙烯醇（PVA），被用作灵活的，半透明的和高导电性的电子和光电器件的材料。研究了不同厚度和不同重量比的共混物的喷雾沉积膜的电导率和光学透射率，以确定用于最佳器件性能和成本的最合适的组合物。我们提出了一种直接的方法来确定最合适的共混物组合物，以生产具有所需的薄层电阻，透光率和成本的聚合物膜，通过使用一个图，该图考虑了共混物组合物和膜厚度的影响，在透光率与薄层电阻图，介导的每单位面积的材料成本。以这种方式，本研究建立了一种经验方法，以确定PEDOT：PSS/PVA共混物组合物被用作光电器件中的电极材料，满足所需的条件的光学透射率，薄层电阻和成本效益。
In this study we propose the use of a blend, comprising poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) and polyvinyl alcohol (PVA), to be used as flexible, semitransparent and highly conductive material for electronic and optoelectronic devices. The electrical conductivity and optical transmittance of spray-deposited films of the blend, in different thicknesses and at different weight ratios, were studied in order to determine the most appropriate composition for optimal device performance and cost. We propose a direct method to determine the most appropriate blend composition to produce polymeric films with a desired sheet resistance, optical transmittance and cost, by using a diagram which considers the influence of blend composition and film thickness in a light-transmittance versus sheet resistance plot, mediated by the material cost per unit area. In this way, the present study establishes an empirical method to determine the PEDOT:PSS/PVA blend composition to be used as electrode material in optoelectronic devices which satisfies the desired conditions of optical transmittance, sheet resistance and cost-effectiveness.
