In this article, novel double-layer films were designed and examined for dye-sensitized solar cells (DSSCs). The commercial titanium dioxide (TiO 2 ) nanoparticles as a bonding underlayer, and the silver nanowires (AgNWs) were used and prepared by means of the polyol method. They which were doped into TiO 2 composite materials. The microstructure of AgNWs and the effect of modified DSSCs on photovoltaic (PV) performance were examined. The experimental research indicated that the localized surface plasmon resonance (LSPR) could enhance light-harvesting efficiency. The exceptional electrical conductivity of silver nanowires also improved the interface resistance of DSSCs. We found that LSPR could substantially boost the incident photon-to-electron conversion efficiency (IPCE) of such DSSCs. The AgNWs@TiO 2 (an optimized content of 3 wt% in photoanode) improved the photovoltaic conversion efficiency ( ${\eta }$ ) of the DSSCs from 4.01% to 5.88%, when compared with the DSSCs without AgNWsy@TiO 2 (pure TiO 2 ).

银纳米线修饰的TiO 2光电阳极的电子传导通道,用于改善染料敏化太阳能电池的界面阻抗

在本文中,针对染料敏化太阳能电池(DSSC)设计并检查了新型双层膜。使用市售的二氧化钛(TiO 2 )纳米颗粒作为粘结底层,并通过多元醇法制备和制备了银纳米线(AgNWs)。掺杂到TiO 2中的它们复合材料。研究了AgNWs的微观结构和改性DSSCs对光伏(PV)性能的影响。实验研究表明,局部表面等离子体共振(LSPR)可以提高光收集效率。银纳米线的出色导电性还改善了DSSC的界面电阻。我们发现LSPR可以大大提高此类DSSC的入射光子-电子转换效率(IPCE)。AgNWs @ TiO 2(在光电阳极中的最佳含量为3 wt%)提高了光电转换效率( $ {\ eta} $ 与不含AgNWsy @ TiO 2(纯TiO 2 )的DSSC相比,DSSC的)从4.01%增至5.88% 。
