Abstract:	摘要： We experimentally and theoretically demonstrated the hierarchical structure of SiO 2 nanorod arrays/p-GaN microdomes as a light harvesting scheme for InGaN-based multiple quantum well solar cells. The combination of nano- and micro-structures leads to increased internal multiple reflection and provides an intermediate refractive index between air and GaN. Cells with the hierarchical structure exhibit improved short-circuit current densities and fill factors, rendering a 1.47 fold efficiency enhancement as compared to planar cells. A hierarchical structure using SiO 2 nanorods and p-GaN microdomes can efficiently enhance the light conversion efficiency of InGaN solar cells. 其他題名： Nanoscale 出版者： England 出版日期： 2012-12-07 出處： Nanoscale, 2012-12, Vol.4 (23), p.7346-7349 識別號： ISSN: 2040-3364 識別號： ISSN: 2040-3372 識別號： EISSN: 2040-3372 識別號： DOI: 10.1039/c2nr32746e 識別號： PMID: 23086234
