dc.description.abstract | Motivated by the reduced material cost and potential high efficiency, laboratory studies have explored ultra-thin crystalline silicon solar cells with thicknesses below 50 micrometres. In this thesis, sub-wavelength periodic nanostructures are developed as compatible surface textures to enhance light absorption in such ultra-thin c-Si solar cells. Through both numerical simulation and experimental studies, this thesis conducts a comprehensive investigation and evaluation of the potential of using sub-wavelength periodic nanostructures for light management applications in ultra-thin c-Si solar cells. By comparing several types of representative periodic nanostructures, important design considerations towards the best optical performance are identified. Those important considerations include the impact of geometry, thickness of the antireflection coating, thickness of the silicon absorber layer and the near-field effect. Experimentally, methods of fabricating novel periodic nanostructures are developed. The optical properties of various periodic nanostructures are also characterized with reference to conventional random-pyramid textures. Both simulation and experimental results demonstrate that periodic nanostructures offer comparable, or even superior, optical performance to conventional random-pyramid textures. | |
