Annealing for intrinsic point-defect control and enhanced solar cell performance : the case of H₂S and tin sulfide (SnS)
This thesis explores the possibility of tin monosulfide (SnS) as a new and promising solar cell absorber material. Out of many other Earth-abundant binary semiconductors, it was selected for study because it has a strong absorption coefficient, high majority carrier mobility, and a promising …

Purity matters : enhancing carrier transport properties in tin sulfide for photovoltaic applications by reducing impurity content
Tin sulfide (SnS), a potential p-type absorber material for photovoltaic applications, is hampered by poor carrier-transport properties, particularly minority-carrier lifetime. This study investigates the role of intrinsic and extrinsic crystallographic point defects on the electronic transport …

Modeling tin sulfide grain growth during post-processing
Tin sulfide (SnS) is a semiconductor material with both an indirect and direct bandgap at 1.1 eV and 1.3 eV respectively. Due to the availability of tin and sulfur, SnS is seen as a feasible alternative to the thin film CIGS and CdTe solar cells. With a direct bandgap of 1.1 eV and the ability to …

Photoconductivity and minority carrier lifetime in tin sulfide and gallium arsenide semiconductors for photovoltaics
… more important to find the greatest inhibiting factor. Through a solar cell simulator program (SCAPS), improvements in the minority-carrier lifetime of cell materials show not only significant improvements in cell efficiencies, but also an un-masking of improvements by other properties, …

Developments in time-resolved ultrafast imaging and spectroscopy at terahertz frequencies
… Over the past few years, it has become more 'routine' to generate and detect THz radiation between 0.1-10 THz, but there remains much room for improvement. In this work, I describe recent developments in THz detection methodology, both in a waveguide platform and in a more typical free space …

Investigation on nanostructured solar cells
… good stability and reproducibility, demonstrating the generation of TiO2 nanoparticles with more flexibility in the control of their properties. The charged droplet size controlled by FFESS is the key variable because it determines the ratio of vapor to liquid phase reactions taking place in …
