在较高工作气压(332.5~399Pa)下,采用等离子增强化学气相沉积(PECVD)工艺制备了优质的本征纳米硅薄膜及掺磷的纳米硅薄膜,并采用X射线衍射(XRD)、拉曼散射(Raman) 测试技术对其进行了测试和分析.结果表明纳米硅薄膜的XRD谱中存在(111)、(220)和(331)峰位;Raman谱中显示出其薄膜中的晶粒的大小(2~5nm)符合纳米晶的要求.将制备的纳米硅薄膜初步用于栅极/ITO/n-nc-Si∶H/i-nc-Si∶H/p-c-Si/Al/Ag结构的异质结(HIT)太阳能电池,开路电压(Voc)达404mV,短路电流密度(Jsc)可达到34.2mA/cm2(AM1.5,100mW/cm2,25℃). 相似文献

聚吡咯/多壁碳纳米管的合成及电化学行为 总被引:1,自引:0,他引:1
在含有多壁碳纳米管(MWCNT)的十二烷基苯磺酸钠(SDBS)溶液中电化学氧化吡咯(Py)制得聚吡咯/多壁碳纳米管(PPy/MWCNT)导电复合膜。研究了聚合温度、电流密度、吡咯浓度对PPy/MWC-NT复合膜沉积量的影响,采用交流阻抗谱(EIS)法研究了该导电复合膜的电化学行为,并用扫描电子显微镜对其表面形貌进行了观察。实验结果表明,随着温度的降低、电流密度及吡咯浓度的增大,复合膜沉积量变大。与纯PPy膜相比,PPy/MWCNT复合膜有更好的电子传递行为,而复合膜表面更加粗糙、疏松。 相似文献

All‐polymer and paper‐based energy storage devices have significant inherent advantages in comparison with many currently employed batteries and supercapacitors regarding environmental friendliness, flexibility, cost and versatility. The research within this field is currently undergoing an exciting development as new polymers, composites and paper‐based devices are being developed. In this report, we review recent progress concerning the development of flexible energy storage devices based on electronically conducting polymers and cellulose containing composites with particular emphasis on paper‐based batteries and supercapacitors. We discuss recent progress in the development of the most commonly used electronically conducting polymers used in flexible device prototypes, the advantages and disadvantages of this type of energy storage devices, as well as the two main approaches used in the manufacturing of paper‐based charge storage devices. 相似文献

H2 additional effect for crystallization of SnO2 films prepared by the hot-wire CVD method was investigated. The crystallization of SnO2 films starts at 170 °C. The selectivity enhancement of the solar cell substrate will contribute to reduce the cost of silicon thin film solar cells. The atomic hydrogen assisted nano-crystallization exists for the depositions of SnO2 films by the hot-wire CVD method. Furthermore, the addition of H2 gas improved the electrical conductivity up to 5.3 × 100 S/cm. However, these effects are limited in the deposition condition of a small amount of hydrogen. Addition of much higher hydrogen concentration starts an etching effect of oxygen atoms. 相似文献
