Optoelectronics And Renewable Energy Research Group

Name : Optoelectronics And Renewable Energy    

                 Research Group


Research Focus:

The aim of forming this group in the department is to initiate and grow research in the area of optoelectronics and renewable energy and, in future, develop devices, systems and processes that would add value to science and technology and national development.

Optoelectronic devices are electrical-to-optical or optical-to-electrical transducers, or instruments that use such devices in their operation. Their operation is based on quantum-mechanical effects of light on electronic materials, especially semiconductors. They are classified into photovoltaic, photoconductive, stimulated emission, radiative recombination and photoemissive devices.

Solar cells, light-dependent resistors, infrared diodes, infrared sensor modules, photodiodes, phototransistors, laser diodes are some of the optoelectronic devices used in a wide range of telecommunications, computers, industry and commercial applications.

On the other hand, renewable energy resources have, for about 4 decades, attracted global attention in view of their potential to complement conventional energy resources which pose the threat of climate change and environmental degradation and are finite in nature.

Solar, wind, hydro and biomass resources have been developed for electricity generation and production of biofuels. More R&D work is needed to improve the efficiencies of devices, systems and production processes to achieve higher outputs of energy production. Energy efficiency and management studies will be carried out using computing and internet technologies.

A 3-tier research and development approach will be adopted namely, devices research, systems research, modeling/simulation studies. At the devices research level, diffusion, ion implantation, epitaxial and other techniques will be used to grow semiconductor layers with varying electrical and optical properties to suit different applications. Part of the systems research will involve research on balance-of-system components such as charge controllers, inverters, batteries etc. Laboratories will be set up for the fabrication and testing of devices and systems. Outdoor testing will be carried out in the actual field operating conditions using state-of the-art equipment which will be acquired from research grants. Collaborations with research groups, institutions and industry within and outside Nigeria will be established in order to enhance research ouput. In addition to laboratory-based research , the group will offer consultancy services in the design, installation and performance evaluation of renewable energy power systems and in energy efficiency studies in the domestic, commercial and industrial sectors.
