项目摘要

The development of organic solar cell requires to solve such issues as, (1) deposition of thin organic films that have high carrier mobility or photo-sensitivity, (2) stacking of organic layers that have carrier transport capability of different charges, (3) thermal stability of the stacked structure, (4) formation of electrode for electron injection into the stacked structure from outer circuit, etc. This research intends to investigate the first three items from the viewpoint of film formation technology, i. e., through the deposition polymerization of carrier transport layers. The fourth item was investigated by the formation of carrier injection layer that has high carrier injection efficiency into the organic layer.Regarding the deposition polymerization, it has been shown that thermally stable polyimide thin films can be obtained without using solvents by the co-deposition of perylenetetracarboxyjic dianhydride and several diamines. The film is expected to have charge transport c … More apability and high optical absorption coefficient coming from the perylene unit. It was also shown that polyurea thin films having azobenzene unit as photoreceptor can be prepared by the co-deposition of azo-containing diamine and diphenylmethane diisocyanate. The dipole orientation of the azobenzene unit can be controlled by the bias voltage on the substrate during the film formation. π-conjugated polymer thin films can be deposited by the co-deposition of biphenylaldehyde and diaminonaphthalene. The film was found to have high conductivity. By the iomzation-assisted deposition of an acrylate monomer that has tetraphenyldiaminobiphenyl unit, hole-transporting polymer thin films were obtained. Since these films can be obtained without solvents, they can be easily stacked with electron transport materials for fabricating organic thin film devices.As for the carrier injection layer, strontium or strontium oxide ultra thin films were prepared at the interface of the cathode and the organic layer. The films were deposited by the ionization-assisted method to the thickness of several nanometers. This method brought about a remarkable improvement of electron injection to the organic layer from the aluminum cathode. Less

有机太阳能电池的开发需要解决此类问题，例如，（1）具有高载流子迁移率或光敏性的薄有机膜的沉积，（（2）具有不同电荷的载体传输能力的有机层堆叠，（3）从堆栈结构中进行堆叠结构的热量构成，（4）从堆叠结构中进行堆栈的形成，等等。地层技术，即通过载体传输层的沉积聚合。通过形成高载体注入效率到有机层的载体注入层的形成，研究了第四项。对沉积聚合进行了重新确定，已经表明，可以通过perylynetetabobboxyjic dianhydride和几个二透析物和几个二径和几个二聚体和几个二胺的共注释，而无需使用溶液来获得热稳定的聚酰亚胺薄膜。预计该薄膜将具有电荷运输C…来自perylene单元的更多能力和高光吸收系数。还表明，具有偶氮苯单元作为光感受器的聚尿素薄膜可以通过含有偶氮二氨酸和二苯基甲基甲烷二异氰酸酯的共沉积来制备。偶氮苯单元的偶极取向可以通过膜形成过程中底物的偏置电压来控制。 π共轭聚合物薄膜可以通过双苯基醛和二苯乙烯的共沉积来沉积。发现该膜具有很高的电导率。通过具有四苯二氨基苯基单元的丙烯酸单体的IOmization辅助沉积，获得了孔传输聚合物薄膜。由于可以在没有溶液的情况下获得这些薄膜，因此可以轻松地用电子传输材料堆叠以制造有机薄膜设备。作为载体注入层，锶或氧化锶超薄膜，在阴极和有机层的界面上制备。膜通过电离辅助方法沉积到几种纳米的厚度。这种方法可以从铝阴极向有机层的电子注入显着改善。较少的
