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.

A new dawn for student governance

The successful and peaceful completion of the University of the Free State’s (UFS) Student Representative (SRC) elections 2011 herals a new dawn for student governance with the announcement of the results today (1 September 2011).

The SRC elections at the Qwaqwa Campus were completed on 25 August 2011, while the elections at our Bloemfontein Campus took place on 29 and 30 August 2011.

“A new dawn heralds a new day when Richard Chemaly, the son of Lebanese immigrants becomes President of an SRC, as elected by students from all racial backgrounds and from across the student body at large. A new day has arrived when candidates could have won voter support across racial lines; a new day is here when all SRC members are now recognised leaders on the basis of academic accountability,” the Dean of Student Affairs, Mr Rudi Buys, says.

A new dawn has arrived; firstly, insofar as student elections for the choice of student leaders at the UFS now proceed according to a non-racial and a non-party political basis.

Not only did the SRC elections at both the Bloemfontein and Qwaqwa Campuses achieve its required quorum, with 31% (4 729 votes) and 50% (2 112 votes) voter turnout, respectively, but the SRC elected by students at the Bloemfontein Campus is 55% black and 45% white, and 60% female and 40% male. The numbers of votes gained by successful candidates also indicate that voters from all racial backgrounds have voted for their candidates of choice.

Secondly, a new dawn has arrived insofar as student governance occupied by only some student groups claiming to speak on behalf of all students has made way for direct voting for candidates by the broad student body and the threefold increase of student governance structures on campus.

Not only did all students at our Bloemfontein and Qwaqwa Campuses (a total of 15 173 and 4 257, respectively) have the opportunity to participate in voting directly, but nine additional Student Councils were established at our Bloemfontein Campus that each holds an ex officio seat on the SRC and allows for student governance in all the major student sectors of the student body, such as for postgraduate students, international students and all categories of student associations.

The various councils now established include the Student Academic Affairs Council, the Student Associations Council, the Postgraduate Student Council, the International Student Council, the Student Media Council, the Residences Student Council, the Commuter Student Council and the Rag Community Service Fundraising and Service Councils. In addition, all faculties also introduced student representative structures at departmental and faculty level in 2011 to ensure student participation in faculty management and governance.

The SRC members at the Bloemfontein Campus are:

Elective portfolios:
President: Mr Richard Chemaly
Vice-President: Mr Lefata David Maklein
Secretary: Ms Matshepo Ramokgadi
Treasurer: Mr Werner Pretorius
Arts & Culture: Ms Alta Grobelaar
Accessibility & Student Support: Mr William Clayton
First-generation Students: Ms Petre du Plessis
Media, Marketing & Liaison: Ms Biejanka Calitz
Sport: Mr Bonolo Thebe
Student Development & Environmental Affairs: Ms Busisiwe Madikizela
Transformation: Ms Qaqamba Mhlauli

Ex officio portfolios:
Dialogue & Ex officio: Associations Student Council: Mr Anesu Ruswa
Academic Affairs & Ex officio: Academic Affairs Student Council: Mr Jean Vermaas
Residence Affairs & Ex officio: Campus Residences Student Council: Ms Mpho Mokaleng
City student Affairs & Ex officio: Commuter Student Council: Ms Annemieke Plekker
Postgraduate Affairs & Ex officio: Postgraduate Student Council: Ms Glancina Mokone
International Affairs & Ex officio: International Student Council: Mr Pitso Ramokoatsi
Student Media Affairs & Ex officio: Student Media Council: Ms Nicole Heyns
RAG Community Service & Ex officio: RAG Fundraising Council: Ms Iselma Parker
RAG Community Service & Ex officio: RAG Community Service Council: Ms Motheo Pooe

In the Qwaqwa elections, SASCO achieved 36,84% of the vote, with SADESMO, PASMA and NASMO each achieving 29,73% and 18,56% and 12,74%, respectively .

Mr Bongani Ncgaca was elected as the President of the SRC at our Qwaqwa Campus, while the names of the SRC members at the campus will be announced on 7 September 2011.

The Central SRC will be established on 8 September 2011 by a joint sitting of the two SRCs.

The successful completion of the SRC elections at the Bloemfontein Campus follows a yearlong review process of student governance by a Broad Student Transformation Forum (BSTF) that consists of 59 delegations from student organisations and residences. The BSTF adopted independent candidacy for elective portfolios and additional student councils to provide ex officio seats on the SRC as the template for student governance, following the consideration of a series of benchmarking reports on student governance nationally and internationally.

The UFS Council adopted the new SRC Constitution, as drafted and submitted by the BSTF, on 3 June 2011.
