为提高聚合物太阳能电池的能量转换效率
将聚乙二醇(PEG)掺入PEDOT:PSS阳极缓冲层
研究了阳极缓冲层修饰对聚合物太阳能电池性能的影响。首先研究了聚乙二醇对PEDOT:PSS薄膜电导率的影响
发现PEG会与PEDOT和PSS相互作用
使得PEDOT链重新排布
有利于电荷载流子的传输
从而显著改善了PEDOT:PSS薄膜的电导率
当PEDOT:PSS中掺入体积分数为2%~4%的PEG时
可得到较大的电导率。然后
以PEG修饰的PEDOT:PSS薄膜作为阳极缓冲层制备了聚合物太阳能电池
研究了PEG的掺入对聚合物太阳能电池性能的影响。实验发现
PEG改善的PEDOT:PSS电导率有利于提高电池的短路电流密度和填充因子
从而改善了器件光伏性能。当PEDOT:PSS中掺入体积分数为2%的PEG时
聚合物太阳能电池的能量转换效率最高
比未掺杂的器件提高了24.4%。
In order to improve the performance of polymer solar cells
polyethylene glycol (PEG) was incorporated into PEDOT:PSS layer
and the effect of anode buffer layer modification on the performance of polymer solar cells was studied. First
the effect of PEG on the conductivity of PEDOT:PSS films was studied
and the results show that PEG interacts with PEDOT and PSS
and reorients the PEDOT polymer chains
which improves the conductivity of PEDOT:PSS layer significantly. PEDOT:PSS layer with 2%-4%(volume fraction) PEG has the optimized conductivity. Then the bulk heterojunction polymer solar cells based on PEG modified PEDOT:PSS anode buffer layer were prepared. It is found that PEG improves the short-circuit current density and fill factor obviously. The polymer solar cell with 2% PEG modified PEDOT:PSS layer gives the maximum power conversion efficiency
as compared with the control device without PEG
24.4% efficiency enhancement is achieved.
