Ouagadougou: Dr. Moussa Ou©draogo has proposed an innovative approach to enhance the efficiency of solar panels by addressing the impact of high temperatures and magnetic fields. To earn his Doctor of Applied Physics degree from Nazi Boni University of Bobo-Dioulasso, Dr. Ou©draogo presented his findings, which emphasize a new mathematical and experimental methodology to predict and improve solar panel performance.

According to Burkina Information Agency, Dr. Ou©draogo's research concluded that thermal and magnetic stresses negatively affect charge carrier transport, reducing photocurrent and limiting the efficiency of radial junction solar cells. His mathematical approach accurately predicts the behavior of optoelectronic parameters under varying thermal and magnetic conditions.

He also developed an experimental method to measure charge carrier lifetime, a crucial factor in evaluating solar cell efficiency. This device enables simultaneous control of temperature and magnetic fields, considering impedance effects for reliable real-world condition measurements.

The research outlines several strategies to enhance radial junction solar cell performance, including the benefits of radial architecture, optimal grain radius determination, and analytical predictions of performance based on environmental factors. It also recommends designing materials to reduce magnetic saturation and integrating a compensation circuit to minimize measurement disturbances. Numerical simulations are advised to optimize cell design, and coupling with thermo-photovoltaic systems is suggested to mitigate heat losses.

The jury, led by Professor Fran§ois Zougmor© from Joseph Ki-Zerbo University, recognized the significance of Dr. Ou©draogo's work by awarding him the degree with highest honors. They highlighted that his research offers theoretical tools, experimental methods, and practical solutions to advance the efficiency and reliability of radial junction solar cells, paving the way for renewable energy development.

The study, directed by Professor Raguilignaba Sam, focused on the characterization of radial junction solar cells under dynamic conditions and explored the influence of magnetic fields and temperature on optoelectronic parameters.
