Three terminal Si-Si:Ge monolitic tandem solar cells
Stand-alone transparent Si solar cell and low band gap Si:Ge solar cell can be applied together in a high performance multi-junction solar cell system to absorb the middle and long wavelength light. In this system, optics needs to be designed carefully for the back side of transparent Si solar cell …

Direct measure of band edge optical absorption of silicon nanostructures using photothermal deflection spectroscopy
… applications. In this thesis, I studied the band edge optical absorption of free standing Si-NPs and Si-NPs in an amorphous silicon matrix, a composite material also known as nano-crystalline silicon (nc-Si:H). In general, it is difficult to directly observe the absorption threshold in these …

Theory and simulation of quantum nanostructures for integrated photonics
… photonic devices, including lasers, electro-absorption modulators (EAMs), single-photon sources, and photodetectors. Theoretical analysis of these devices is required to enable performance improvements and support development for novel applications. In this thesis, we employ the …
