- W764559603 abstract "In this dissert, we want to study the improvement of light trapping mechanism due to grating grown its surface in order to achieve higher efficiency at higher incidence. Firstly, we adopt a numerically stable mathematical calculation called rigorous coupled-wave analysis, RCWA, to optimize the profile of grating structure. Then we realize it onto real InGaP/GaAs/Ge III-V MJ solar cell. Lastly, the efficiencies will be measured under standard AM1.5G solar spectrum at various incidences. In general, the experiment results of samples with grating present higher efficiency than those without. Better performance can also be achieved at larger oblique incidence. Surprisingly, the efficiencies follow the trend of transmittance rate as RCWA has estimated. Although it is quite complicated to judge the relation categorically; we can still attribute the improvements of increasing photon penetrating to grating mechanisms. As a result, if we can find another more effective and less costly way during fabrication process, the contribution of this light trapping structure could be widely extended due to the light tracking system and terrestrial applications have become more prosperous in recent years." @default.
