为了确定目前有机光伏(OPV)材料的输出能力，重要的是知道所用半导体配方的理论最大涂覆速度。在这里，我们对几种与有机太阳能电池相关的原型有机半导体油墨的涂层稳定性窗口进行了全面的研究。涂层稳定性窗口首先由速度高达10m/min的片材对片材涂布机实验确定。建立了基于“涂层窗口套件2010”软件的数值模拟模型，以深入了解涂层在较高速度下的稳定性极限。分析了在水/异丙醇混合物中的PEDOT：PSS[poly(3，4-ethylenedioxythiophene)：poly(styrenesulfonate)]以及在氯苯、邻二甲苯和四氢萘中的P3HT：PCBM[poly(3-hexylthiophene-2，5-diyl)：Phenyl-C61-butyric酸甲酯，表明涂层速度可能高达60m/m in。模拟进一步揭示了给定湿膜厚度时的最大涂布头部距离。最后，根据模拟数据得到的参数，设计了一种槽芯镀膜PEDOT：PSS和P3HT：PCBM层的太阳电池，表现出了合理的性能。(C)2012爱思唯尔B.V.保留所有权利。
To determine the output capability of present organic photovoltaic (OPV) materials, it is important to know the theoretical maximum coating speeds of the used semiconductor formulations. Here, we present a comprehensive investigation of the coating stability window of several prototype organic semiconductor inks relevant for organic solar cells. The coating stability window was first determined experimentally by a sheet to sheet coater at velocities of up to 10 m/min. A numerical simulation model based on the "Coating Window Suite 2010" software was established to give insight into the coating stability limitations at higher coating velocities. An analysis of PEDOT:PSS [poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)] in a water/isopropyl alcohol mixture as well as P3HT:PCBM [poly(3-hexylthiophene-2,5-diyl):Phenyl-C61-butyric acid methyl ester] in chlorobenzene, o-xylene and tetrahydronaphthalene showed the possibility of coating speeds up to 60 m/min. The simulation further revealed the maximum coating head distances for a given wet film thickness. Finally, we show a solar-cell with slot-die coated PEDOT:PSS and P3HT:PCBM-layer based on the parameters obtained by the simulated data, which exhibits reasonable performance. (C) 2012 Elsevier B.V.
