Optimisation of the grating height, periodicity and fill-factor yielded an enhancement of 5.3% in Jsc over the reference cell.Keywords: Dielectric diffraction gratings; Fill-factor; Finite-difference time-domain simulation; GaAs quantum wells; Light-trapping; Optimisations; Quantum well solar cells; Rectangular strips; Diffraction; Finite difference time domain method; Gallium arsenide; M201210.1109/COMMAD.2012.64723942016-02-24
