研究目的
To prepare water-based and viscous screen-printing inks composed of conducting polymer PEDOT:PSS and insulating halloysite nanotubes as a filler (HNTs) with different organic additives for use as counter electrodes in dye-sensitized solar cells (DSSCs).
研究成果
Screen-printed PEDOT:PSS/HNTs counter electrodes with 1 wt% of HNTs showed improved electrical conductivities, thermal stability, and photovoltaic performance in DSSCs compared to pure PEDOT:PSS electrodes. The best DSSCs reached a conversion efficiency of 4.5%, indicating the potential of PEDOT:PSS/HNTs inks for scalable manufacturing of next-generation hybrid photovoltaics.
研究不足
The requirement of higher drying temperature for PEDOT:PSS/HNTs inks may limit their application on thin polymeric substrates which tend to change their shape above temperatures around 130 °C.
