UNLABELLED
Highly conductive, flexible, and transparent electrodes (FTEs) of
PEDOT
PSS films on plastic substrates have been achieved using strong acid treatments. However, it is rare to realize a performance attenuation of
PEDOT
PSS FTEs on plastic substrates and flexible optoelectronic devices because of strong acid residues in the
PEDOT
PSS matrix. Herein, we develop a feasible transfer-printing technique using mild acids. Because of a mild and weak property of these acids and less acid residues in
PEDOT
PSS matrix, the transferred
PEDOT
PSS FTEs exhibited a significant enhancement in stability, conductivity (3500 S cm(-1)), transparency, and mechanical flexibility on plastic substrates. Flexible organic solar cells with the FTEs also showed a remarkable enhancement in power conversion efficiency and stability in the ambient atmosphere. It is expected that the novel transfer-printing technique for making
PEDOT
PSS FTEs is also useful in many other types of flexible optoelectronic devices.

使用强酸处理，在塑料衬底上实现了聚 3,4-乙烯二氧噻吩：聚苯乙烯磺酸盐（PEDOT: PSS）薄膜的高导电、柔韧和透明电极（FTE）。然而，由于 PEDOT: PSS 基体中的强酸残留，很少能实现塑料衬底上 PEDOT: PSS FTE 和柔性光电设备的性能衰减。在此，我们使用弱酸发展了一种可行的转印技术。由于这些酸的温和和微弱性质以及 PEDOT: PSS 基体中的酸残留较少，转移的 PEDOT: PSS FTE 在塑料衬底上表现出稳定性、导电性（3500 S cm(-1)）、透明度和机械柔韧性的显著提高。具有 FTE 的柔性有机太阳能电池在环境气氛中的功率转换效率和稳定性也得到了显著提高。预计用于制造 PEDOT: PSS FTE 的新型转印技术对于许多其他类型的柔性光电设备也很有用。
