The mechanism of thin film Si nanomachining using femtosecond laser pulses
… illumination and the melting of the substrate. Since the laser does not directly heat the substrate, and there has been no directly observed heat affected zone (HAZ) nor vaporization, fs laser ablation is sometimes considered to be a direct solid-vapor phenomenon. Recent research indicates that …

Technological assessment of light-trapping technology for thin-film Si solar cell
… (DG) and Anti-Reflection Coating (ARC) for thin film Si solar cell was analyzed from the technology, market, and implementation perspectives. Two applications were investigated. For monocrystalline thin film Si solar cell, layer transfer technology is too expensive, while sliver Si …

Thin-film silicon solar cells : photonic design, process and fundamentals
… converting solar energy into electricity. Thin-film silicon solar cells are believed to be a promising candidate for further scaled-up production and cost reduction while maintaining the advantages of bulk silicon. The efficiency of thin-film Si solar cells critically depends on optical …

High efficiency thin film silicon solar cells with novel light trapping : principle, design and processing
One major efficiency limiting factor in thin film solar cells is weak absorption of long wavelength photons due to the limited optical path length imposed by the thin film thickness. This is especially severe in Si because of its indirect bandgap. This thesis invents a novel light trapping scheme, …

Modeling of Joule heating and thermoelectric transport in thin film silicon for SJEM measurement
This thesis reports the finite element modeling of a quantitative nanometer-scale temperature distribution along the doped Si devices. The modeling replicates data acquisition technique of Scanning Joule expansion microscopy (SJEM). Time varying heat equations and Maxwell’s equations are solved in …
