Limiting Efficiency of Perovskite Solar Cells

– Limiting Efficiency of Perovskite Solar Cells – ABSTRACT The power conversion efficiency of perovskite solar cells has risen from as low as 3.8% to as high as 19.3% in just five years with yet a projected value of over 20% in the next few years by experimentalists. Such a tremendous breakthrough is one of […]

Fundamentals of Laser Dynamics

Fundamentals of Laser Dynamics. ABSTRACT The thesis presents the modeling and simulation of three types of lasers namely; Semicondoctor laser, Solid state laser and CO2 laser. The rate equations were derived and simulated to examine the dynamic behaviour of the three types of lasers under investigation. The result shows that the Semicondoctor laser has the […]

Calculations of Phonons and Phonon Dispersion in Lifep Pnictide Superconductor

Calculations of Phonons and Phonon Dispersion in Lifep Pnictide Superconductor. ABSTRACT Not too long ago(2008),a new pnictide Superconductor free from arsenic was discovered –LiFeP. It belongs to the family of the so called ‘111’ type iron Superconductor. It has unique characteristics in its normal state which can be useful in understanding the unusual high temperature […]

The Design of an On-Chip Silicon Photonic Diode

The Design of an On-Chip Silicon Photonic Diode. ABSTRACT This work presents numerical calculation of electromagnetic waves in unidirectional on-chip silicon optical diodes. An original optical diode, designed by Wang et. al. [Opt. Express. 19, 26948-26955 (2011)], is based on breaking of spatial inversion symmetry and the directional band gap difference of two 2D photonic […]
