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.

UFS hosts a successful New Music Indaba
2015-08-18

  

Held at the University of the Free State’s Odeion School of Music (OSM), the NewMusicSA’s New Music Indaba 2015 featured works which Clare Loveday described as “breathtaking, discreet, and perfectly balanced.”

Loveday, one of South Africa’s acclaimed music critics and was Composer-in-Residence for the annual Johannesburg International Mozart Festival, attended the Indaba from 21-26 July 2015. In a review of Saturday’s gala concert, she referred to recitals of this nature as an “essential part of the South African musical landscape, providing musicians and composers a space in which to express their world.”

Staff and students of the OSM were extensively involved in facilitating the festivities as a symbol of commitment to South Africa and international contemporary art music. The OSM Camerata under the baton of Xavier Cloete performed two works by South African composer Hendrik Hofmeyr well as a work by young Argentinian composer Diego Soifer entitled Mille Regretz .The festival featured music theory lectures, a variety of workshops, roundtable discussions ,concerts as well as an outreach programme.

Loveday described the highlight of her Indaba experience as “A delicate construction of sounds and silences that drew the listener into a focused and intense sound world,” a highlight created by the visiting German composer, Charlotte Seither’s “Far From Distance” for piano, clarinet, and cello. The concert evening culminated with Diale Mabitsela's "Friday Nights at Six," adding to the spectacular nature of the festival.

Throughout the week, classical chamber works featuring South African New Music Ensemble (SANME), the Choir of Christ Church Arcadia, and the Odeion Vocal Consort were performed and well-received. Bringing the five-day event to a conclusion was a choral mass at the Bloemfontein Anglican Cathedral, featuring an “Agnus Dei” written by George T. King.
 
Douglas Scott, Curator of the 2015 Indaba, reflected on it as a great success, saying that, “most of the participants agreed the event was a wonderful opportunity simply to hear different voices from the composition community juxtaposed with one another.”

From Scott’s perspective, the principal goal was to foster communication between artists with different visions, and to reach out to the local community.
