Abstract :
We present a study of antireflective schemes and their operation over a full day. We compare simulation results for single and double layer antireflective coatings with bio-mimetic moth-eye structures, taking into account the full range of wavelengths and incident angles experienced by fixed solar cells from sunrise to sunset. We show that solar cells incorporating antireflective moth-eye arrays could produce up to 12% more energy than those employing single layer antireflective coatings
