为了利用该分子在这一方法膨松，重要的是要知道用于通过旋涂成膜的条件。首先，在p型和n型半导体必须能溶解在溶剂中。当一些物质仍然存在，这将成为光活性层大核心域。建议使用个别的溶剂的适当的商业过滤以除去剩余的材料。接着，在其中分子溶解该前体溶液必须被均匀地和均质打印为在大约60秒在ITO /玻璃基板上的光敏层。这个过程是用以下三个步骤执行。首先，将前体溶液和ITO /玻?...

有机光电器件被认为是有前途的可再生能源，由于其制造成本低，重量轻1-7。因为这些优点，有大量的科学家一直沉浸在此希望的领域。在过去十年中，染料敏化型，有机薄膜，和钙钛矿敏化太阳能电池已在这方面取得了8中的功率转换效率显著进展。 具体而言，有机薄膜太阳能电池和BHJ有机薄膜太阳能电池技术是用于太阳能的利用效率和成本效益的解决方案。另外，能量转换效率达到10％以上与使用低带隙聚合物作为电子给体和富勒烯衍生物作为电子受体（苯基-C 61 -丁-酸甲基酯：[60] PCBM或苯基-C 71 -丁酸甲酯：[70] PCBM）9-11。此外，一些研究人员ħAVE已经报道，在光活性层，其具有低带隙的聚合物和富勒烯衍生物的构造获得高总体效率的BHJ结构的重要性。然而，富勒烯衍生物是空气敏感。因此，空气稳定的电子接受材料是必需的作为替代。一些报道曾建议新类型使用n型半导体聚合物或金属氧化物作为电子受体的有机光伏电池。这些报告的支持空气稳定，自由富勒烯，有机薄膜太阳能电池12-15的发展。 然而，与此相反富勒烯系统或n型高分子半导体的系统，从而获得的BHJ结构的光活性层，其具有电荷分离和电荷传输能力的一个令人满意的性能，是在金属氧化物系统16-17困难。此外，富勒烯衍生物和n型半导体聚合物具有高的溶解度在许多溶剂。因此，很容易通过选择油墨溶液作为溶剂，它是光活性层18-20的前体，以控制所述光活性层的形态。与此相反，在与供电子聚合物组合使用金属醇盐体系的情况下，两个半导体是在几乎所有的溶剂不溶。这是因为金属醇盐不具有在溶剂中的高溶解度。因此，溶剂的形态控制的选择性非常低。 在这篇文章中，我们报道了利用分子蓬松制作打印和高空气稳定BHJ太阳能电池控制光活性层的形态的方法。我们描述了自由富勒烯BHJ太阳能电池的进展形态学控制的重要性。

morphology control for fully printable organic&#8211;inorganic bulk-heterojunction solar cells based on a ti-alkoxide and semiconducting polymer

The photoactive layer of a typical organic thin-film bulk-heterojunction (BHJ) solar cell commonly uses fullerene derivatives as the electron-accepting material. However, fullerene derivatives are air-sensitive; therefore, air-stable material is needed as an alternative. In the present study, we propose and describe the properties of Ti-alkoxide as an alternative electron-accepting material to fullerene derivatives to create highly air-stable BHJ solar cells. It is well-known that controlling the morphology in the photoactive layer, which is constructed with fullerene derivatives as the electron acceptor, is important for obtaining a high overall efficiency through the solvent method. The conventional solvent method is useful for high-solubility materials, such as fullerene derivatives. However, for Ti-alkoxides, the conventional solvent method is insufficient, because they only dissolve in specific solvents. Here, we demonstrate a new approach to morphology control that uses the molecular bulkiness of Ti-alkoxides without the conventional solvent method. That is, this method is one approach to obtain highly efficient, air-stable, organic-inorganic bulk-heterojunction solar cells.
