掺杂PEDOT∶PSS对聚合物太阳能电池性能影响的研究
Influence of doped PEDOT∶PSS on performance of polymer solar cells
摘要
Abstract
In this paper,we investigate the doping effect on conductivity of poly（3,4-ethylene dioxythiophene）：poly （styrenesulphonic acid）（PEDOT∶PSS）and its influence on performance of polymer solar cell.The experiment demonstrates that the conductivity of PEDOT∶PSS is improved obviously by doping polar solvent dimethyl sulfoxide （DMSO）.The maximum of the conductivity is 1.25 S/cm when the doping concentration reaches 10 wt%,which increases about three orders of magnitude compared with the undoped.Based on doped PEDOT∶PSS used as an anode buffer layer,the polymer solar cell （ITO/PEDOT∶PSS/P3HT：PCBM/LiF/Al） shows an improvement of hole charge transport as well as an increase of short-circuit current density and a reduction of series resistance,owing to the higher conductivity of the doped PEDOT∶PSS.Consequently,it improves the whole performance of polymer solar cell.The short-circuit current density （Jsc） of 11.09 mA·cm-2,the open circuit voltage （Voc） of 0.63 V,and the fill factor （FF） of 63.7% are obtained under 100 mW/cm2 air-mass solar simulator illumination,yielding a 4.45% power conversion efficiency （η）.关键词
