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.

Housing strategy must accommodate special needs
2005-10-17

Dr Mark Napier of the Council for Scientific and Industrial Research (CSIR) 

South Africa’s housing strategy must give attention to people with special needs, including people with disabilities as well as people living with HIV / AIDS and those in poverty.

This was the view expressed by Dr Mark Napier of the Council for Scientific and Industrial Research (CSIR) during his recent presentation to the Housing Research Day organised by the Centre for Development Support (CDS) at the University of the Free State (UFS).

Dr Napier previously worked in the national Department of Housing and was involved in shaping the recently launched “Breaking New Ground” housing strategy of Minister Lindiwe Sisulu. 

He said the changing social and demographic trends in South African society, especially after 11 years of democracy, required more flexibility in housing delivery to address the housing needs of different groups of people.  “For example, there are people who wish to or may be required to be spatially mobile because of their work or other reasons. There are also those communities who are vulnerable to disasters,” he said.

According to Dr Napier, housing delivery faced a number of challenges which needed to be addressed, including:

  • the withdrawal of larger construction firms
  • perceptions of low profit margins in the private sector
  • the slow process of developing an emerging contractor sector
  • access to bridging and other finance
  • the ability to retain capacity and expertise mainly at municipal level
  • the acquisition of well located (especially inner city) land

Dr Napier said the new housing strategy – which is called “Breaking New Ground” – tries to go beyond the provision of basic shelter to the establishment of sustainable settlements. It is also tries to be more responsive to housing demand rather than being supply led.

 The new strategy also allows for greater devolution of power to municipalities in the provision of housing, through accreditation to manage subsidies, Dr Napier said. 

He said a survey of people who had benefited from government’s housing programme had shown mixed results, with beneficiaries reporting a sense of security, independence and pride.  Although the location of the houses was poor and there were increased costs, most beneficiaries said they were better off than before, according to the survey.  Beneficiaries also highlighted the problem that they had very little personal choice between houses, sites or settlements.

There was also the perceived failure of developers and municipalities to repair defective houses or adequately maintain settlements, the survey found.
Many beneficiaries also reported that they felt unsafe in their settlements as well as in their own houses.

Prof Lucius Botes, the director of the Centre for Development Support, said the research day highlighted the Centre’s ability to interact with real problems faced by communities, by government, the private sector and civil society.  “This is how we can ensure that the UFS is engaged through our research with our people’s problems and challenges and enables the UFS as a place of scholarship to assist in finding solutions,” Prof Botes said.
