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.

Get ready for celebrating with a cause at the University of the Free State (UFS). After an external review and internal consultation process, our “giving back” will get a fresh new look. Our RAG, as you know it, will have a new name and format going forward. 

Innovative thinking will align the UFS Student Affairs, RAG Community Services (RCS), Community Engagement (CE), and Services Learning (SL) to deliver suitable contributions for current community needs. We will guide the alignment process with an integrated framework for learning and developmental outcomes. If the RCS, CE, SL, and Student Affairs align their specific programmes and activities to achieve the same developmental outcomes, we believe that the collective effect will be enhanced. You get further if you pull in the same direction, rather than various good-intentioned movements on different routes. 
 
Stronger together An Institutional Committee for Civic and Social Responsibility (CSR) will act as the overarching structure for accountability, alignment, and advice to the RCS, CE and SL divisions. In a collective effort, four exciting programmes will take flight.

1 Schools project for first-year students Mentored by senior students, groups of first-year students will be assigned to, and participate in local school projects. Students will learn to solve problems and work together in small groups as they collaborate on a specific community project involving primary or secondary schools in the Mangaung region. 

2 Community gardens This project will help individual student communities to begin and maintain their own vegetable gardens to address food insecurity within their own environment.

3 Eco-vehicle project for senior students The aim of the eco-vehicle project is to create an interdisciplinary experience. Undergraduate senior students from a Student Life College (SLC) can work together to build an eco-vehicle from waste material. The track day, along with creative pit stops, will take place on 16 February 2018, preceding the Community celebration of 17 February 2018.

4 Community celebration To foster good relationships between the UFS and the community, we aim to host an annual celebration that will be open to the broader Mangaung community. The celebrations will kick off on the morning of 17 February 2018 with a business relay and a showcase of the eco-vehicles. The festive day will conclude with an evening music concert. 

We have yet to rename “RAG”, and while this creative process is brewing, you can look forward to paying it forward with value! Any suggestions with regard to a new name for our new process can be forwarded to scheepersk@ufs.ac.za 

Name suggestions will be accepted until 30 November 2017.
