With the same active layer thickness, the ultimate efficiency of a solar cell integrated with an optimized PQC nanohole array can be enhanced by 9.01% and 1.40% compared to that with an ordered square lattice of a nanohole array and a random nanohole array, respectively. The absorptance enhancement is mainly due to the higher-order rotational symmetry in PQC structures, which leads to the presence of additional resonant modes, the broadening of existing modes and the reduction of surface reflectance. The angular response for both transverse-electric and transverse-magnetic modes are also analyzed in detail.This work was supported by the Australian Research Council Discovery Early Career Researcher Award (DE 130101700) and the National Natural Science Foundation of China (No. 11104130).6 pages2015-02-2010.1088/2040-8978/17/3/0359012016-06-14
