We report on the implementation of stainless steel foils coated with dispersed Single Wall Carbon Nanotubes as novel, low cost and highly efficient counter electrodes for dye sensitized solar cells (DSSCs). We use commercially available non purified nanotubes dispersed in water by ultrasonication and drop cast on stainless steel substrates. When implemented on a ruthenium based DSSC we obtain a high short circuit current density (J(sc)= 9.21 mA cm(-2)), a good open circuit voltage (V(oc) = 0.660 V) and a solar energy conversion efficiency of 3.92%. The above cited values are measured under a light flux of 100 mW cm(-2) generated by a solar simulator equipped with a filter AM 1.5. The obtained results are comparable to those attained using a stainless steel counter electrode sputtered with a 2 microm thick platinum film (J(sc) 10.92 mA cm(-2), V(max) = 0.66 V and eta = 4.5%, AM 1.5).
我们报告了一种新型的、低成本、高效率的染料敏化太阳能电池（DSSC）对电极，其采用不锈钢箔片上涂覆分散的单壁碳纳米管。我们使用商业上可获得的未经纯化的纳米管，通过超声分散在水中，并滴铸在不锈钢基底上。当应用于基于钌的 DSSC 时，我们获得了高短路电流密度（J(sc)=9.21 mA cm(-2))，良好的开路电压（V(oc) = 0.660 V)和太阳能转换效率为 3.92%。上述值是在配备 AM 1.5 滤波器的太阳能模拟器产生的 100 mW cm(-2)光通量下测量的。得到的结果与使用溅射 2 微米厚的铂膜的不锈钢对电极（J(sc) 10.92 mA cm(-2)，V(max) = 0.66 V 和 eta = 4.5%，AM 1.5）获得的结果相当。
