|
Abstract:
聚(3,4-乙撑二氧噻吩):聚苯乙烯磺酸盐(PEDOT:PSS)具有良好的导电性和柔性，在可穿戴的柔性电致变色器件和柔性太阳能电池中显示出巨大的潜力。通过不同的化学沉积和物理掺杂可以更大的提高PEDOT:PSS的电化学性能。目前PEDOT:PSS在有机太阳能电池(Organic solar cells, OSCs)空穴传输层(HTL)的应用研究极为广泛，但是其具有低电导率、水/氧敏感、腐蚀电极等缺陷。为了追求优异的性能，常用的PEDOT:PSS空穴传输层仍需优化。本文综述了近年来PEDOT:PSS的各种改善方法和在有机太阳能电池空穴传输层中的应用研究最新进展，并介绍了PEDOT:PSS在柔性有机太阳能电池的应用。
Poly (3,4-ethylenedioxythiophene): Polystyrene sulfonate (PEDOT:PSS) has good electrical conductivity and flexibility, and shows great potential in wearable flexible electrochromic devices and flexible solar cells. The electrochemical properties of PEDOT:PSS can be greatly improved by different chemical deposition and physical doping. At present, PEDOT:PSS has been widely applied in the hole transport layer (HTL) of organic solar cells, but it has some defects such as low conductivity, water/oxygen sensitivity, corrosion electrode and so on. In order to pursue excellent performance, the commonly used PEDOT:PSS hole transport layer still needs to be optimized. In this paper, the application of PEDOT:PSS in organic solar cells is reviewed, and the different deposition methods of PEDOT:PSS and the method and mechanism of improving the performance of organic solar cells by composite films are introduced.
