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.

Kovsies beat Pukke at USSA tennis tournament
2010-01-13

 The Kovsies women’s team that participated in last year’s USSA tennis tournament were, from the left, front: Elrien de Villiers and Nicola Dormehl; middle: Rensia Henning and Christine Keyser; back: Jeanne du Plessis and Elizna Barnard.

 

The men who participated in the tournament were, from the left: Willem Steenkamp, PW Holtzhausen, Duke Munro, Janine de Kock (manager), Marnus Kleinhans (coach), Divan Olivier, HB Steyn and Reon Henning.
 

Last year Kovsie tennis concluded on a highlight when the men’s tennis team of the University of the Free State (UFS) won the USSA tournament that was held in Grahamstown for the first time in twenty years. The UFS women’s team also excelled by going through to the final round, where they had to bow the knee before the team of Stellenbosch University.

The result of these excellent achievements was that two of the five players that were selected for the USSA women’s training group were Kovsies. They are Rensia Henning and Christine Keyser. Elrien de Villiers was selected as the player of the tournament but unfortunately she could not be included in the group because she is a Namibian citizen.

The men’s group existed of eight players, of which four are Kovsies. They are Reon Henning, Duke Munro, Willem Steenkamp and PW Holtzhausen.

Members of the USSA training group will participate in training camps, tournaments and trials to prepare for the Confederation of University and College Sport Association (CUCSA) games (where all the Southern Africa countries participate) in Botswana that will take place from 5-11 July 2010. The training group will also participate in the World Student Games in 2011.

The Kovsies men’s team kick-started last year’s USSA tournament by beating the team from the University of Cape Town with 6-1 and later on the same day beating the team from the University of Johannesburg with 5-1. The next day they beat the team from the Tshwane University of Technology with 7-0 and the team of the University of Pretoria with 5-1. According to Ms Janine de Kock from KovsieSport at the UFS this is an excellent achievement, taking into account that Tukkies had ended in second place at the 2008 tournament.

In the semi-finals Kovsies played against the North-West University and beat them with 4-1. After this triumph in the singles matches the organisers decided that the doubles would not be played.

The women’s team won their matches against the Universities of Pretoria, Cape Town, Rhodes, KwaZulu-Natal and the Tshwane University of Technology. The tournament ended with Kovsies and Maties as the only two unbeaten teams and Stellenbosch University walked away with the laurels. The North-West University did not have a women’s team at the tournament at all.
