Mr Bart Roose
University of Cambridge
The majority of the energy produced today is generated by burning fossil fuels, causing climate change and pollution. Additionally, fossil fuels are predicted to run out within the next 100 years. In order to keep the planet habitable and sustain the quality of life for future generations we will have to develop clean and renewable energy alternatives.
The biggest drawback for renewable energy sources so far has been their relatively high cost. The sun provides us with an abundance of energy, of which we only need to harvest a tiny fraction to satisfy the global demand for energy. My work focuses on a novel technology for harvesting solar energy, the so-called perovskite solar cell, which promises lower production costs, which will help to make renewable energy more competitive. The major challenge for this emerging technology is the limited device lifetime and the focus of my work will thus be to improve the lifetime of perovskite solar cells, which will be essential for the commercialization of this emerging technology.
I will be doing this by investigating the role of tin dioxide (SnO2) as an electron transporting material in perovskite solar cells. I will explore new ways to chemically modify this material to achieve more stable and efficient devices, with the ultimate aim of producing clean, affordable and renewable energy.
