Angle resolved photoemission study of surface states on the Pt(997) vicinal surface
Ayieta, Elijah; Carvell, Jeff; Cheng, Ruihua; Losovyj, Ya. B (University of Nairobi, 2010)One-dimensional atomic chains can be synthesized on stepped surfaces and the electronic structure of the high vicinal surface plays an essential role in determining the physical properties of atomic chains grown on top of ... -
A Simplified Method for Parameter Determination of a Photovoltaic Module using Manufacturer’s data
Ndegwa, Robinson; Ayieta, Elijah; Simiyu, Justus; Odero, Nicodemus (University of Nairobi, 2020)Accurate and fast modelling and simulation of Photovoltaic module requires careful determination and identification of the unknown parameters required in fitting the voltage-current and power-voltage curves to replicate ... -
A Simplified Simulation Procedure and Analysis of a Photovoltaic Solar System Using a Single Diode Model
Ndegwa, Robinson; Ayieta, Elijah; Simiyu, Justus; Odero, Nicodemus (University of Nairobi, 2020)A single diode model for a photovoltaic solar module is the most ideal and quick way of analyzing the module characteristics before implementing them in a solar plant. Solar modules manufacturers provide information for ...
