Numerical Study of the Thermal Performance of Three Roof Models in Hot and Dry Climates
Windé Nongué Daniel Koumbem1*, Issaka Ouédraogo2, Wend Dolean Arsène Ilboudo2, Pèlèga Florent Kieno1
The thermal performance of three roofing models: tile, corrugated and earth terrace is numerically analyzed. The mathematical equations which govern the three roofing models are established by the electrical method of analogies. These equations are discretized by an implicit finite difference method and solved by the Gauss-Seidel algorithm. We(...)

Modeling the response of an illuminated polysilicon solar cell under the influence of radio waves, a 3D approach
Vinci de Dieu Bokoyo Barandja, Bienvenu Magloire Pakouzou, Emmanuel Wendsongré Ramdé, Jean M’boliguipa, Mamoudou Saria, Martial Zoungrana, Issa Zerbo
This work investigated the response of an illuminated polysilicon PV cell under AM radio waves. Using a 3 D analysis, the equations which describe the movement of excess electrons and their space and time behavior were solved in order to first find the density of the excess electrons and to subsequently derive the current density and the volta(...)

Investigating the Effect of Inclination Angle of Magnetic Field Vector on Silicon PV Modules
Dioari Ulrich Combari , Emmanuel Wendsongré Ramde, Bruno Korgo, Ramatou Saré, Martial Zoungrana , and Issa Zerbo
In earlier studies, we have shown theoretically and experimentally that magnetic fields (MFs) have negative impact on silicon PV module (photovoltaic module). A noticeable decline in photocurrent with a slight increase in photovoltage was observed. Also, how those fields affected other key module’s parameters was also studied. These studies co(...)

Parameters Degradation Analysis of a Silicon Solar Cell in Dark/Light Condition using Measured I-V Data
Dominique Bonkoungou, Toussaint Guingane, Eric Korsaga, Sosthène Tassembedo, Zacharie Koalaga, François Zougmore, Arouna Darga
In this paper, we investigate and analyze parameters degradation in a typical photovoltaic (PV) cell, which lead to power loss under dark as well as light condition using measured current-voltage (I-V) data. A nonlinear least squares method to extract the parameters such as the reverse saturation currents, the ideality factors, the series and(...)

Quadratic Boost Converter: An Analysis with Passive Components Losses
Modou Badiane, Prince Abdoul Aziz Honadia Bernard Zouma, Fabé Idrissa Barro
The Cascaded Connected Single Switch Quadratic Boost (C2S2-QB) is studied first from its ideal model, then with semi-real model taking into account resistive losses through the inductors and the capacitor. The continuous conduction mode equations, describing these different models are established, taking into account losses through passive com(...)
