With a constant increase in the price of electricity, any innovation to replace this necessity in our daily lives is welcome. 

The University of the Free State (UFS), whose vision is supported by an element of innovation, welcomes the recent agreement between its Department of Physics and Ghent University.

Attractive solution

Not only will this research – which aims to develop the materials necessary for transparent solar panels – enlarge the international research footprint of the UFS, but it is also an attractive solution to address the energy demands of buildings, electric motor vehicles, and mobile electronics without affecting their appearance.

According to Prof Hendrik Swart, from the UFS Department of Physics, the agreement between the two universities entails a joint doctoral degree in which both universities will supervise the project and the awarding of the doctorate. The student, Lucas Erasmus, will conduct research at both institutions.

Transparent solar panel

The idea with the research is to develop glass that is transparent to visible light, just like the glass you find in the windows of buildings, motor vehicles, and mobile electronic devices. However, by incorporating the right phosphor materials inside the glass, the light from the sun that is invisible to the human eye (ultraviolet and infrared light) can be collected, converted, and concentrated to the sides of the glass panel where solar panels can be mounted. This invisible light can then be used to generate electricity to power these buildings, vehicles, and electronic devices. The invention is therefore a type of transparent solar panel.

Implemented in cellphone screens

This technology can be implemented in the building environment to meet the energy demands of the people inside the buildings. 

The technology is also good news for the 4,7 billion cellphone users in the world, as it can be implemented in the screens of cellphones, where the sun or the ambient light of a room can be used to power the device without affecting its appearance. 

Another possible application is in electric cars, where the windows can be used to help power the vehicle.

Low-income housing

Erasmus added: “We are also looking at implementing this idea into hard, durable plastics that can act as a replacement for zinc roofs.” 

“This will allow visible light to enter housing, and the invisible light can then be used to generate electricity. The device also concentrates the light from a large area to the small area on the sides where the solar panels are placed; therefore, reducing the number of solar panels needed and, in return, reducing the cost.”

The technology will take about a decade to implement.

“This study is currently ongoing, and we are experimenting and testing different materials in order to optimise the device in the laboratory. After this, it needs to be upscaled in order to test it in the field. It is truly the technology of the future,” said Erasmus.

Cornell academic focuses on international trade in inaugural lecture at the UFS

Prof Muna Ndulo, Professor at the Cornell Law School, delivered his inaugural lecture as Extraordinary Professor in the Department of Mercantile Law at the University of the Free State (UFS). The topic of his lecture was: Facilitating regional and world trade through international trade.

With this topic, Prof Ndulo said that trade is a recognised contributor to the Growth Domestic Product of countries and its role can be used to reduce global poverty and inequality. “Although Africa’s GDP is 5-6% on average, with a positive increase in direct foreign investments, its meaningful participation in world trade has been decimal,” he said.

Trade between African countries is 12%, which is the lowest in the world. This is in comparison to intercontinental trade in European states (72%), North America (48%), Asia (52%) and 26% in Latin America. The EU and USA are Africa’s key export markets. High transport costs, import substitution, intra-regional transactions, conflict of rules and bills of exchange remain as challenges. There are also no common standards with regards to the development of manpower as an important factor in production.

Prof Ndulo suggested solutions which Africa can use to achieve harmonisation. This includes the introduction of normative rules designed in a framework of a treaty. A modern law approach could be used to develop legislation and ensure uniformity; and lastly, the formulation of commercial customs and practice. “Harmonisation demands a high level of expertise and quality research,” said Prof Ndulo.

He added: “When legislation is developed, it must resemble the needs of our trade laws in order to maximise benefits.”

He concluded that, for harmonisation to be achieved, the political environment must play a major role in regional and world trade.

Prof Elizabeth Snyman-Van Deventer, Head of the Department of Mercantile Law, made sincere closing remarks on how much we as a continent have become an enemy of our own self by not having trade relationships among ourselves as Africans. Prof Snyman urged those in the legal fraternity to be part of the harmonisation of trade laws and eliminate the barriers by improving legislation.
