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.

Central SRC constitution for UFS approved by Council
2005-07-20

University of the Free State Fact Sheet

1. The Council of the University of the Free State (UFS) on 10 June 2005 unanimously approved the establishment of a Central Student Representative Council (CSRC)  to constitute a legitimate basis for the democratic participation of students of all three of its campuses in the governance of the university.

2. In a major breakthrough and transformation step for student governance, the Central SRC will include representatives of the main campus in Bloemfontein, the Vista Bloemfontein campus and the Qwaqwa campus of the UFS.

3. The need to establish the Central SRC follows the incorporation of the Qwaqwa campus into the UFS in January 2003 and the incorporation of the Vista campus in Bloemfontein into the UFS in January 2004.

4. The constitution of the Central SRC is the outcome of a consensus reached during a lengthy process of negotiation between the SRCs of the three UFS campuses, indirectly involving diverse student formations such as Sasco, ANCYL, YCL, Pasma, SASO, SADESMO, AZASCO, SCO, HEREXVII, KovsieAlliance, ACDP, etc. Independent constitutional and political experts facilitated key parts of the negotiation process.

5. In this process, the UFS management went out of its way to ensure the participation of all student formations, especially Sasco and the ANC Youth League, as well as the duly elected SRC officials of the three campuses.

6. With the establishment of a Central SRC, the UFS has adopted a federal student governance model whereby the CSRC is the highest representative student body on matters of common concern for all students. The three campuses of the UFS will retain SRC structures for each campus with powers and responsibilities for matters affecting the particular campus.

7. The central SRC will have 12 members made up of delegates of the different campus SRCs, including the presidents of these three SRCs. In total, the main campus will have 5 representatives, the Qwaqwa campus will have 4 representatives and the Vista campus will have 3 representatives. This ratio ensures a strong voice for the smaller campuses in the central SRC.

8. This arrangement will be reviewed after a year to make allowance for the phasing out of undergraduate (pipeline) students at the Vista campus, as was agreed in the negotiations preceding the incorporation of that campus into the UFS.

9. From these 12 members a central SRC president will be chosen on a quarterly basis to represent the general student body at Executive Management, Senate and Council.

10. The historic official inauguration of the first Central SRC is scheduled to take place in early August 2005.

11. This event, like the adoption of a broadly negotiated new constitution for the main campus SRC, represents a  breakthrough in that all three campus SRCs delegations and all relevant student organizations have been part of the process and have accepted the outcome of the process.
