The UNESCO Chair in Sustainable Energy Technologies (SET) is dedicated to the development of low-cost, efficient and sustainable solar technologies. It focusses on their manufacture and use within a circular economy in Africa and low and middle income economies.

In collaboration with colleagues at Swansea and partners across these regions, Professor Matthew Davies is co-ordinating a network to develop next-generation printable photovoltaic technologies for low and middle-income countries.

The Chair was awarded in 2024 for an initial four-year period.

The Challenge

One of the greatest challenges facing humanity is the generation of clean, affordable, and reliable renewable energy. This task is vital for sustainable development and addressing global challenges and opportunities.

Nowhere is this more important than across the continent of Africa – an area blessed with abundant solar energy, natural wealth and a resourceful and innovative labour force. Yet, more than 500 million people lack access to electricity and many more endure fuel poverty or suffer inconsistent energy supplies.

Emerging technologies like printable photovoltaics are well-positioned to make an impact – particularly organic and perovskite devices, which promise high-efficiencies and low material and processing costs.

However, renewable systems and components are rarely designed with the specific needs of low and middle-income economies in mind. This can lead to failure of technologies and generation of hazardous electronic waste in places where there are few facilities to treat it safely.

How the Chair addresses these issues

The aim of this Chair is to equip local communities with the knowledge and tools to harness the sun’s energy, transform waste into wealth, and build a brighter future through truly sustainable photovoltaic technologies.

As an international collaborative network, it advances the development of emerging photovoltaic technologies for low- and middle-income economies.

Critically, it links the technical and engineering aspects of their development with broader considerations such as circular economy principles, social issues, and education.

Three principles underpin the Chair's work

Professor Matthew Davies

Professor Matthew Davies holds the UNESCO Chair in Sustainable Energy Technologies. He is Professor and Head of Applied Photochemistry and Circular Economy at Swansea University.

Professor Davies also holds the position of Honorary Professor in the University of KwaZulu-Natal. He is a Fellow of the Royal Society of Chemistry (RSC) and President of its Environment, Sustainability and Energy Community Council

He researches the photochemistry of materials for low-cost photovoltaic applications, with the aim of improving stability, light-harvesting efficiency and performance. This mainly focusses on perovskite solar cells but also dye-sensitised solar cells­­­­ and organic photovoltaics. Matthew is particularly interested in re-manufactured devices and materials and processes to enable re-use and re-manufacture within a circular economy.
