报道了在n型GaAs(111)B衬底上分子束外延生长Au辅助GaAs p型掺杂NW阵列及其光伏特性。样品在520至580 °C范围内的不同衬底温度下生长。结果表明,在衬底温度为550 °C时,转换效率对衬底温度的依赖性最大。对于最佳样品,获得了1.65%的转换效率和25%的填充因子。
We report on the molecular beam epitaxy growth of Au-assisted GaAs p-type-doped NW arrays on the n-type GaAs(111)B substrate and their photovoltaic properties. The samples are grown at different substrate temperature within the range from 520 to 580 °C. It is shown that the dependence of conversion efficiency on the substrate temperature has a maximum at the substrate temperature of 550 °C. For the best sample, the conversion efficiency of 1.65% and the fill factor of 25% are obtained.
