Solar power in our country scientists research high-performance flexible organic solar cells

Flexible electronics, especially the optoelectronic devices based on organic materials, is a trend in the development of the future electronic devices, and wind power projects in henan has a great application prospect. Compared with the dry preparation, solution processing method was used to prepare flexible electrode has low cost and can be large-scale & other; For rewinding & throughout; Printing preparation etc, and huge potential for development. Flexible transparent electrode are usually using dry or solution preparation process. Single junction and laminated flexible organic solar cells for 13, respectively. 1% and 16. The photoelectric conversion efficiency of 5%, and exhibited excellent mechanical properties, bending 1000 times in a row, the device can remain more than 95% of the initial efficiency. Automotive heat exchange system & other; To obtain high performance of flexible transparent electrode is the precondition of efficient flexible organic optoelectronic devices, is a core problem at present in the field. The flexible transparent electrode achieved excellent performance, low surface roughness, and with excellent mechanical properties and thermal stability as well as the preparation method is simple and green. Institute of chemistry of nankai university professor jiangyin office manager team recently successful preparation at the same time with high conductivity, high transmittance and low surface roughness of the silver nanowires flexible transparent electrode, be used to build the flexible organic solar cells, the photoelectric conversion efficiency refreshed the flexible organic/polymer solar cells reported in literatures of photoelectric conversion efficiency of record. ” Jiangyin office manager said. At the same time, however, how to obtain a high conductivity, high transmittance and low surface roughness and the preparation method is simple, flexible transparent electrode of ideal heat exchange green, is still a huge challenge. To prove its practicability in organic optoelectronic devices, jiangyin office manager team on-board controller based on the flexible transparent electrode was prepared flexible organic solar cells. Because of the lack of the high performance of the flexible transparent electrode, the flexible organic photovoltaic device performance still lags behind that of the corresponding rigid device significantly. This achievement makes efficient flexible organic solar cells from one step closer to realize industrialization. ” Jiangyin office manager said. Jiangyin office manager team used high polymer electrolyte, the preparation of the wind power projects in henan step with & other; Class throughout the grid &; The structure of the silver nanowires flexible transparent electrode. Preparation of flexible photovoltaic devices and use commercial ITO glass electrode device performance. 4, top international academic journals 'nature & middot; Electronics, they are introduced in the field of flexible transparent electrode and the flexible organic solar cell research gained breakthrough. “ In addition to organic solar cells, the low cost high performance flexible transparent electrode in other flexible electronics, such as organic light-emitting diodes, transistors, sensors, and other fields will also have great potential applications. Research shows that the electrode can be applied to different types of active material and single junction and laminated photovoltaic devices.
