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.

Science school of excellence for Grade 11 learners launched

The Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) has launched a project to give top Grade 11 learners an idea of what the faculty has to offer by giving them a ‘university-type’ experience.

The Science School of Excellence Project was launched last week during a function where the university’s schools support programmes were introduced to the management and members of staff.

The project is aimed at Grade 11 learners in the Free State who obtained an overall average of 80% in the 2008 Grade 10 final examinations. This includes a minimum score of 80% (Level 7) in Mathematics and a minimum score of 80% (Level 7) in Physical or Life Science during the same examination. It will be presented on the Main Campus in Bloemfontein from 6-9 July 2009. The closing date for applications is 8 May 2009.

“By presenting this project we want to stimulate learners’ interest in the natural and agricultural sciences, give them an idea of what we have to offer, raise their interest to come and study at the UFS and let them know that we cherish them as role models in their schools and as academic leaders of the future,” said Prof. Neil Heideman, Vice-Dean of the Faculty of Natural and Agricultural Sciences at the UFS.

According to Prof. Heideman the Science School of Excellence will take on the form of small lab and field projects which the learners will carry out under the supervision of staff and postgraduate students. An application fee of R50 per learner must be paid by the school and a maximum of 80 learners can be accommodated. The 80 learners will be selected on a first come, first served basis and a registration fee of R200 per learner has to be paid after they have received notice that they have been accepted. Letters in this regard have been sent to principals of secondary schools in the Free State. “We will also include 10 learners from disadvantaged rural schools, who will be fully sponsored,” said Prof. Heideman.

“Fourteen of our departments will be presenting programmes, during which learners will engage in challenging exercises that will be ‘out of school’ experiences involving laboratory experiments and research activities typical of our faculty,” said Prof. Heideman.

Five other schools support programmes of the UFS were also presented during last week’s launch function. They were the Itjhoriseng Project, which is a skills development course in Mathematics and Physical Sciences for teachers in the Further Education phase; the Science for the Future Project that aims to encourage more learners to enter into science-related studies and careers; the Qwaqwa School Support Programme that aims to improve the year-end results of Grade 12 learners and a project by the South African Foundation for Economic and Financial Education (SAFEFE) and the National Council of Economic Education (NCEE),which aims to improve the economic and financial literacy of teachers.

“The university’s role in the development of teachers and learners in various subject fields has increased tremendously over the past couple of years. Learners are our students of the future. As a university we must do as much as we can to equip them and their teachers with the necessary skills to better themselves,” said Rev. Kiepie Jaftha, Chief Director: Community Service at the UFS at the launch of the Science Schools for Excellence Project.
