Research on Photovoltaic Properties of Heterojunction Photovoltaics Cells with ZnO Nanstructure on Si Substrate

采用化学气相沉积的方法在p型Si衬底上生长了n型ZnO纳米棒,并在此基础上制备了Si基ZnO纳米结构异质结光伏电池。器件的平均反射率约为5%,电池具有良好的整流特性。同时发现取向较好的ZnO纳米结构的电池具有好的转换效率,最好样品的转换效率为2.6%,填充因子为45%。

N-type ZnO Nanorads grous on P-type Si substrate by using the chemical wheather deposition method.Based on these,the heterojuction photovolatics cells with ZnO Nanostructures on Si substrate are made.The average reflectance of the devices is 5%,the cell has rectifying behavior.At the same time,it is shown that the ZnO Nanorods structure cells with better orientation have good conversion efficiency,for the best sample,the conversion efficiency of 2.2% and the fill factor of 45% are obtained.
