A revolutionary new type of window glass – in effect a transparent solar panel - is the objective of joint research being done by the University of the Free State (UFS) in South Africa and Ghent University in Belgium. 

A working model has been created which proves the viability of the process which now needs to be refined, made more efficient and brought to the market. It is hoped to achieve this within a decade.

This new product will have the capacity to revolutionise the generation of power cheaply from the sun to power homes, factories and cities in a new clean way.

Academics from the UFS, Prof Hendrik Swart and Lucas Erasmus are doing joint research with Ghent University in Belgium, to find solutions for energy production. 

The two universities entered into an agreement recently for this research into electricity generation. The research is driven by the UFS and was prompted by ever-rising electricity prices and growing demand for electricity production. South Africa lives with constant power outages which leaves people stuck in lifts and facing chaos on the roads as traffic lights cut out. Many people who can afford them now rely on generators.

Prof Hendrik Swart, senior professor in the Department of Physics at the University of the Free State and SARChI chair (South African Research Chairs Initiative) in Solid State Luminescent and Advanced Materials, says: “An innovation like this which can help to replace traditional means of carbon based fuel for power generation in our daily lives would be hugely welcome.”

Swart explains the main objective of the research: “The idea 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 buildings, vehicles and electronic devices. The goal is therefore to create a type of transparent solar panel.”

Swart says 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 cell phone users in the world, as it can be implemented in the screens of cell phones, where the sun or the ambient light of a room can be used to power the device without affecting its appearance,” he said.

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

Lucas Erasmus who is working with Prof Swart adds: “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 diffused 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.”

It is envisaged that the technology will take about a decade to refine and implement. This study is currently on-going, and UFS are experimenting and testing different materials in order to optimise the device in the laboratory. It then needs to be upscaled in order to test it in the field. “It is truly the technology of the future,” says 
Erasmus.

The UFS envisages that the end result of this research will provide an attractive solution to address the energy demands of buildings, electric motor vehicles and mobile electronics without affecting their appearance. 

According to Swart, the agreement entails a joint doctoral degree in which both universities will supervise the project and the awarding of the doctorate. Lucas Erasmus, a student at the UFS, has been tasked with the assignment to conduct research at both institutions.

In January 1, 2003, the Qwa-Qwa campus of the University of the North (Unin) was incorporated into the University of the Free State (UFS).

FREDERICK FOURIE

IN January 1, 2003, the Qwa-Qwa campus of the University of the North (Unin) was incorporated into the University of the Free State (UFS).

While this is merely the beginning of a long and complex process, it does represent a major milestone in overcoming the apartheid legacy in education, realising the anti-apartheid goal of a single non-racial university serving the Free State.

The incorporation is also part of the minister's broader restructuring of the higher education landscape in South Africa - a process which aims to reshape the ideologically driven legacy of the past.

In contrast to the past educational and social engineering that took place, the current process of incorporating the Qwa-Qwa campus of Unin into the UFS is informed by three fundamentally progressive policy objectives, clearly outlined in the education white paper 3: (A framework for the transformation of higher education):

To meet the demands of social justice to address the social and structural inequalities that characterise higher education.

To address the challenges of globalisation, in particular the role of knowledge and information processing in driving social and economic development.

To ensure that limited resources are effectively and efficiently utilised, given the competing and equally pressing priorities in other social sectors.

Besides informing the way the UFS is managing the current incorporation, these policy objectives have also informed the transformation of the UFS as an institution over the past five years.

In 2001, former president Nelson Mandela lauded the success of the UFS in managing this transformation, by describing the campus as a model of multiculturalism and multilingualism. This was at his acceptance of an honorary doctorate from the UFS.

Indeed our vision for the Qwa-Qwa campus as a branch of the UFS is exactly the same as it is for the main UFS campus - a model of transformation, academic excellence, community engagement and financial sustainability, building on the histories and strengths of both the Qwa-Qwa campus and the UFS (Bloemfontein campus).

Realising this vision will be a giant leap forward in establishing a unified higher education landscape in the Free State.

In more concrete terms, the UFS is working towards this vision by focusing on the following areas of intervention: access and equity; academic renewal; investment in facilities; and sound financial management.

These interventions are being made not to preserve any vestiges of privilege or superiority, but precisely to increase access for students from poor backgrounds and to promote equity and representivity among all staff.

The current growth phase of the UFS has seen student enrolment almost double over the past five years, in particular black students, who now constitute approximately 55 percent of the student population of nearly 18 000 (including off-campus and online students).

But it has not just been a numbers game. Our approach has been to ensure access with success.

Our admissions policy, coupled with the academic support and "career preparation" programmes we offer, have resulted in significant successes for students who otherwise would not have been allowed to study at a university.

This will be continued at Qwa-Qwa as well.

Our academic offerings too have undergone dramatic change. We have become the first university in the country to offer a degree programme based on the recognition of prior learning (RPL).

This is not just a matter of academic renewal but of access as well, especially for working adults in our country who were previously denied a university education.

As for the sound financial management of the UFS (including the Qwa-Qwa campus), this is being done not for the sake of saving a few rands and cents, but for the greater value to our society that comes from having sustainable institutions.

It is sustainable universities that can make long-term investments to fund employment equity, provide information technology for students, upgrade laboratories, construct new buildings, develop research capacity, and provide a safe environment for students and staff, as is happening now at the UFS.

As a result of such management, a practical benefit for prospective students at the Qwa-Qwa campus of the UFS will be lower academic fees in some cases compared with the Unin fees.

As is the case with all these processes, there are concerns from staff and students at Qwa-Qwa and the broader community of the region that the Qwa-Qwa campus serves.

To get the campus viable and to ensure its continuation in the short term, tough choices had to be made by the minister of education regarding which programmes to offer and fund.

But we have been encouraged by the community's understanding that these concerns can be addresed over time as the campus becomes financially viable.

Meetings between the top mangement of the UFS and community representatives, staff and students at Qwa-Qwa have laid the basis for building a climate of trust in such a complex process.

We should not be captives of the past divisions but build this new unified higher education landscape that can meet our country's developmental needs.

It should be a higher education landscape that is based on broadening access, promoting equity and social justice, developing academic excellence, and the effective and efficient management of scarce resources. This should be our common common objective.
