中文摘要：

采用金属援助刻蚀和溶液填充的方法，构筑了原理型Si／导电聚合物（聚3，4-乙撑二氧噻吩：聚苯乙烯磺酸盐，PEDOT1 PSS）核壳纳米线阵列光伏电池。电池的光伏转换效率不依赖于入射光强，达到了6．8％。改变入射光角度，表征了电池的广角光伏转换性能。入射角在45°范围内的有效光电转换效率相对于正入射的光伏转换效率仅降低12％。实验结果表明，纳米线阵列结构的光伏电池有益于广角太阳能转换。

英文摘要：

The efficient Si/conducting polymer of poly（3,4-ethylenedioxythiophene） ：poly（styrenesulfonate） （PEDOT： PSS） core/shell nanowire array solar cells have been fabricated by metal-assisted Si chemical etching followed by a PEDOT： PSS solution filling and drying process. The power conversion efficiency （PCE） of the hybrid solar cell is independent of incident intensity and reaches 6. 8%. The wide-angle photovoltaic conversion property is characterized by changing incident angle. The conversion efficiency with the incident angle less than 45° is only reduced by 12% compared with under nromal incidance. The hybrid solar cells show excellent wide-angle photovoltaic conversion performance.
