With her talk on ‘Breaking the walls of darkness’, Emmie Chiyindiko came in second out of the 74 pitches presented at the recent Falling Walls Science Summit.

“I need you to take a moment and imagine trying to do everything that you do every day … without reliable energy. Or I’ll ask you this … How far would you walk to charge your phone if you didn’t have electricity? Would you walk for hours? Kilometres?”

“Well, that’s what millions of people in sub-Saharan Africa do daily to charge their phones. One billion people globally don’t have access to electricity in their homes and in sub-Saharan Africa, more than half of the population remains in the dark.”

This was the introduction to Emmie Chiyindiko’s talk at the recent Falling Walls Science Summit earlier this month. Emmie, who is a PhD student in Chemistry at the University of the Free State (UFS), came in second out of the 74 pitches presented with her talk on ‘Breaking the walls of darkness’ in the ‘Breakthrough of the year in the emerging talents category’.

Falling Walls Lab is a world-class pitching competition, networking forum, and steppingstone that brings together a diverse and interdisciplinary pool of students, researchers, and early-career professionals by providing a stage for breakthrough ideas, both globally and locally. 

Emmie, who sees getting out of bed every morning as just another opportunity to “be the exceptional young black female scientist that I am”, won the local Falling Walls Lab in Cape Town in October, which resulted in her going through to the finals in Berlin. She plans to host the Falling Walls Lab in Zimbabwe, her homeland, next year. 

This innovator and science communicator, whose work has been covered in Forbes Science, News24, and the Sunday Times, among others, refers to her obtaining second place on the international stage for her research as “a tremendous achievement and a new height in my science communication career. That level of recognition from the world leaders in science, technology, and science engagement cannot be overstated”.

Ending energy poverty

She believes Sustainable Development Goal 7 – leaving no one behind and eradicating global poverty – must be preceded by intentional efforts to end energy poverty. “My research on dye-sensitised solar cells (DSSC) with special metal complexes is among the most interesting alternatives to conventional solar cells.”

Emmie explains: “The design of the cells is inspired by photosynthesis – that good old process plants use to transform sunlight into energy via chlorophyll. Instead of a leaf, the cells start with a porous, transparent film of eco-friendly titanium dioxide nanoparticles. The film is also coated with a range of different dyes that absorb scattered sunlight and fluorescent light. When sunlight hits, it excites the electrons in the dye, creating an endless supply of energy. 

The bright side of this research is that there are several benefits to this invention. It produces energy that is cheap, reliable, and relatively simple and inexpensive to produce. Emmie adds: “These next-generation cells also work impeccably in low-light and non-direct sunlight conditions, providing all-year-round energy with no disruptions. DSSC is also three times cheaper than conventional cells and produces 40% more energy.”

Improving livelihoods 

She continues: “It does not degrade in sunlight over time as do other thin-film cells, making the cells last longer, and requiring less frequent replacement. DSSCs are also mechanically strong, because they are made of lightweight materials and do not require special protection from rain or abrasive objects.”

Emmie has proven that solutions to our current energy situation are available. “We are on the cusp of an energy revolution, and we must act now. Solutions are available, and if we do not seize them during a time of crisis, when will we?”

She believes that creating technology like this can end the energy crisis and improve livelihoods. “Billions of people simply lack enough energy to build a better life. Affordable, abundant, and reliable energy can go a long way to store food, power life-saving medical equipment, and run trains and factories. It can help communities to grow and prosper and to access opportunity and dignity. Societies where people have access to energy have lower childhood mortality, a higher life expectancy, they eat better and drink cleaner water, and have a better literacy rate.”

Open letter from Prof Jonathan Jansen to all UFS students
2014-02-22

Dear Students of the University of the Free State

In the past four years there has emerged a new consensus on the three campuses of the University of the Free State (UFS) about the things that divide us – such as racism, sexism and homophobia. Students and campus leaders have worked hard to develop this new consensus in residences and in the open spaces on campus. There can be no doubt that new bonds of friendship have developed across the markers of race, ethnicity, class, religion and sexual orientation. I bear witness to these new solidarities every day on the campus.

You chose a white student to head up the transformation portfolio on the SRC. You chose a black captain to head up the university’s first team in rugby. You chose a white “prime” as head of residence to lead a predominantly black men’s residence. You chose a South African woman of Indian descent as Rag Queen and last week, a black student from Cape Town as the men’s Rag winner—choices not possible and never made before in our campus history. Many of you have intimate friends who come from different social or cultural or religious backgrounds. You learn together, share rooms together, pray together and party together. In other words, in the day to day workings of this university campus, you have demonstrated to campus, city and country that we can overcome the lingering effects of racism and other maladies in this new generation. You have helped create a university community inclusive of people of diverse religions, abilities, class and sexual orientation.

I have said this repeatedly that from time to time this new consensus will be tested – when a minority of students, and they are a small and dwindling minority, still act as if these are the days of apartheid. And when that consensus is tested as it was this week, and as it will be tested in the future, only then we will be able to assess the strength and durability of our progress in creating a new South African campus culture of human togetherness based on respect, dignity and embrace.

The real test of our leadership, including student leadership, is how we respond when our transformation drive is threatened.

Let me say this: I have absolute faith in you, as students of this great university, to stand together in your condemnation of these vile acts of violence and to move together in your determination to maintain the momentum for the Human Project of the University of the Free State. We have come too far to allow a few criminals to derail what you have built together in recent years.

There will, no doubt, be unscrupulous people on all sides of the political spectrum wanting to milk this tragedy for their own narrow purposes. There will be false information, rumours and exaggerations by those who wish to inflame a bad situation to gain mileage for their agendas. That is inevitable in a country that is still so divided.

I ask you, through all of this, to keep perspective. Two or ten or even twenty students behaving badly do not represent 30,000 students; a minority of violent and hateful persons do not represent the ideals, ambitions and commitments of the majority. At the same time, let us be realistic – anyone who thinks you can drive transformation without resistance clearly does not understand the difficult process of change.

The events of the week remind us, however, that we still have a long road to walk in deepening social and academic transformation at our university. Yes, we have invested hundreds of hours in training and mentorship; we have created new structures – such as the Institute for Reconciliation and Social Justice – to capture the energy and imagination of students driving transformation; we have created many opportunities for students to study and travel on this and other continents to enable cross-cultural learning; we have established formal and informal opportunities to dialogue about difficult issues on and off campus between students and their leaders; and we crafted new curricula to enable teaching and learning on the big questions of our times.

But this is clearly not enough, and so I have decided on the following immediate next steps:
  1. We will meet for several hours next week to think about how we can deepen the transformation of our university after this terrible incident.

  2. We will arrange a University Assembly on the events of the past week so that we speak with one voice on human wrongs and to re-commit to human rights and we will continue with open forum discussions during the months to come.

  3. We will review the entire spectrum of programmes, from orientation to residence life to the undergraduate curriculum, to determine how effective our interventions really are in reaching all students with respect to basic issues of human rights.

  4. We will review our media and communications strategy to determine how far and deep our messages on human rights travel across all sectors of the university community. In this regard it is important that the campus be blanketed on a regular basis with our condemnation of human wrongs and our commitment to human rights.

  5. We will commission the Institute for Reconciliation and Social Justice to review the events of the past week and make recommendations on how we can improve the campus environment so that all students are protected from harm inside residences, classrooms and in open spaces of the campus.

  6. We will take the questions raised during this week into the academic community and to the general staff of the university so that all personnel also engage with our own roles and responsibilities with respect to campus transformations.

  7. We undertake to make annual report-backs on transformation to all stakeholders in public forums so that students and staff and external communities can track the progress of the university on matters of human rights on campus.

I wish to thank my staff for acting firmly as soon as this tragic event came to our attention. We worked through the night to find and identify the perpetrators. We traced the two students and immediately handed them to the police. They were expelled. And throughout this process we offered counselling and support to the victim of this violent act.

The two former students were expelled and will now face justice in the criminal courts. It is hoped that in the course of time they will come to their senses and seek restoration and reconciliation with the student they so callously harmed. They are not part of the university community anymore.

That is the kind of university we are.
