摘要
聚合物poly(3,4-ethylenedioxythiophene):polystyrene sulfonate(PEDOT:PSS)是一种具有高电导率和良好透过性的p型半导体材料。PEDOT:PSS/Si杂化太阳电池由于具有较低的工艺温度,且工艺简单而具有一定的前景。在这种杂化太阳电池结构中,PEDOT:PSS的光学、电学性质对器件性能有重要影响。分别从PEDOT:PSS退火工艺、溶液二次掺杂(二甲基亚砜)的含量以及PEDOT:PSS薄膜厚度3个方面对薄膜的光、电特性以及器件性能的影响进行研究,并优化相关工艺。根据这些优化的参数,最终得到6.63%的太阳电池转化效率(太阳电池面积为2.25 cm^2)。
Polystyrenesulfonate(PEDOT:PSS) is a p-type semiconductor material with high conductivity and good permeability. PEDOT:PSS/Si hybrid solar cell is promising for it has lower preparation temperature and easier preparation process. For such hybrid solar cell,the electrical and optical properties of PEDOT:PSS are significant. This paper investigate the effects of PEDOT:PSS annealing process,secondary doping concentration(dimethyl sulfoxide)and PEDOT:PSS film thickness on the performance of PEDOT:PSS films and PEDOT:PSS/Si solar cells. Based on these optimized parameters,6.63% of the cell conversion efficiency were obtained(area is 2.25 cm^2).
