Dr Chibuisi Okorieimoh is a researcher and technical staff member at the School of Physics, Clinical & Optometric Sciences, Technological University Dublin, whose work focuses on renewable energy technologies, photovoltaic (PV) system performance, and energy policy in developing and developed regions. His research combines materials science, system performance analysis, and policy evaluation to promote sustainable and equitable energy transitions.

He has published extensively on the long-term durability, performance degradation, and transient behaviour of solar PV systems, with studies such as “Long-Term Durability of Solar Photovoltaic Modules” and “Comparison of Predicted and Measured Annual Performance of a Rooftop Grid-Connected PV System in the Irish Climate.”

Dr Okorieimoh also investigates the policy and regulatory challenges influencing decentralised renewable energy deployment in sub-Saharan Africa, providing comparative insights into governance frameworks and electrification initiatives in Nigeria, Liberia, and Malawi.

His early research on Ba-doped ZnO thin films explored nanostructured semiconductors for optoelectronic applications. His broader research interests include PV system performance, renewable energy policy, thin-film materials, and sustainable energy transitions.

Dr Chibuisi Okorieimoh’s research interests lie at the intersection of renewable energy technologies, photovoltaic (PV) performance analysis, and sustainable energy policy. His work aims to enhance the understanding of solar PV system behaviour, improve durability and efficiency, and inform policy frameworks that support equitable energy transitions.

Key areas of interest include:

• Photovoltaic (PV) System Performance and Reliability – Long-term performance assessment, degradation and loss rate analysis, transient behaviour, and seasonal variability in grid-connected and rooftop PV systems.

• Renewable Energy Materials – Synthesis and characterisation of thin-film and nanostructured semiconductors, including doped ZnO materials for optoelectronic and photovoltaic applications.

• Energy Policy and Regulation – Comparative analysis of decentralised renewable energy policies, governance frameworks, and regulatory challenges in sub-Saharan Africa and other emerging markets.

• Sustainable Electrification and Just Energy Transitions – Strategies for inclusive access to clean energy through decentralised and community-based renewable systems.

• Performance Modelling and System Optimisation – Bridging experimental data with predictive models to improve PV deployment efficiency across diverse climatic and socioeconomic contexts.
