Abstract We report on the development of a cost effective, highly transparent flexible conductive electrode for energy conversion devices using the ITO/PEDOT:PSS nanocomposite. The ITO/PEDOT:PSS nano composite thin film was deposited via bar coating, then its characteristics were examined. In particular, we study any changes in its transparency and resistance. The thin film transparent ITO/PEDOT:PSS was annealed using a low temperature annealing technique called plasma annealing. The purpose of low temperature plasma annealing is to help excite the electrons from their bonding states in the valence band into the antibonding states of the conduction band where a second order phase transition occurs. This study investigates the influence of O2 plasma annealing on the resistance of the nano composite thin films. The included PEDOT:PSS supports the flexibility of the ITO, as pristine ITO is brittle. High optical transmittance of 93.73% at 550 nm and a reduction in the sheet resistance were achieved using this plasma annealing from 1105 Ω/□ to 535 Ω/□ on the ITO/PEDOT:PSS nano composite making them excellent candidates to develop as cost effective flexible transparent electrodes that can be used as thin film heaters.

低温等离子体退火对柔性、透明和导电的 ITO/PEDOT:PSS 复合电极的影响

摘要 我们报告了使用 ITO/PEDOT:PSS 纳米复合材料为能量转换设备开发具有成本效益、高度透明的柔性导电电极。采用棒涂法沉积ITO/PEDOT:PSS纳米复合薄膜，并对其特性进行研究。我们特别研究了其透明度和阻力的任何变化。使用称为等离子体退火的低温退火技术对薄膜透明 ITO/PEDOT:PSS 进行退火。低温等离子体退火的目的是帮助将电子从价带中的键合态激发到导带的反键合态，在那里发生二阶相变。本研究调查了 O2 等离子体退火对纳米复合薄膜电阻的影响。包含的 PEDOT：PSS 支持 ITO 的灵活性，因为原始的 ITO 很脆。在 550 nm 处实现了 93.73% 的高透光率和薄层电阻的降低，在 ITO/PEDOT:PSS 纳米复合材料上使用从 1105 Ω/□ 到 535 Ω/□ 的等离子体退火使它们成为开发具有成本效益的优秀候选材料可用作薄膜加热器的柔性透明电极。
