It is reported a kind of solution-processible transparent conductive film consisting of reduced graphene oxide (rGO) nanosheets and silver nanowires (AgNWs). The sandwiched structure of rGO/AgNWs/rGO is readily deposited via layer-by-layer blade-coating on the rigid glass or flexible PET substrate at mild annealing temperature. The rGO nanosheets sandwiching the AgNWs networks not only induce close contact of the AgNWs networks as a clipper to improve the conductivity, but also link the discrete AgNWs as a connector to improve the uniformity of the film conductivity. The transparent rGO/AgNWs/rGO film exhibits sheet resistance as low as 14.29 Ω/□ with transmittance over 90% at 550 nm. Moreover, the rGO/AgNWs/rGO composite film shows good ambient stability due to the rGO coverage and the existing charge interaction between AgNWs and rGO. Polymer solar cells are fabricated on the transparent rGO/AgNWs/rGO-coated glass or flexible PET substrates and they exhibit comparable photovoltaic perfromance to the control devices fabricated on the commercial ITO substrate. More importantly, the PSCs based on the rGO/AgNWs/rGO/PET substrate show more excellent flexibility than that of the device based on the ITO/PET substrate.

据报道，一种可溶液处理的透明导电膜由还原的氧化石墨烯（rGO）纳米片和银纳米线（AgNWs）组成。rGO / AgNWs / rGO的夹层结构很容易在温和的退火温度下通过逐层刮刀涂层沉积在刚性玻璃或柔性PET基板上。夹着AgNWs网络的rGO纳米片不仅引起AgNWs网络之间的紧密接触，从而提高电导率，而且将离散的AgNWs连接成一个连接器，从而提高了薄膜电导率的均匀性。透明的rGO / AgNWs / rGO薄膜在550 nm处的薄层电阻低至14.29Ω/□，透射率超过90％。此外，rGO / AgNWs / rGO复合膜由于rGO的覆盖以及AgNWs和rGO之间现有的电荷相互作用而显示出良好的环境稳定性。聚合物太阳能电池在透明的rGO / AgNWs / rGO涂层玻璃或柔性PET基板上制造，其光伏性能与在商用ITO基板上制造的控制装置相当。更重要的是，与基于ITO / PET基板的设备相比，基于rGO / AgNWs / rGO / PET基板的PSC具有更好的柔韧性。
