Dr. Antonio Abate sets up a new Helmholtz Young Investigator Group to improve life span of perovskite solar cells
Dr. Antonio Abate
Dr. Antonio Abate sets up a Helmholtz Young Investigator Group at Helmholtz-Zentrum Berlin and moved to Berlin a few days ago. His aim: He wants to improve Perovskite solar cells which are one of the most promising material classes to be discovered in the last few years. The scientist will study the materials and interfaces of perovskite solar cells in order to improve their long-term stability.
Antonio Abate came out on top in a highly competitive selection process of the Helmholtz Association and will now receive 300,000 euros per year in funding over a period of five years. He researched, among other places, at the Universities of Oxford and Cambridge in England. He then received a Marie-Skłodowska-Curie grant to work at the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland. He currently heads the photovoltaic activities at the Adolphe Merkle Institute of the University of Fribourg, Switzerland.
Aims of the Young Investigator Group “Active Materials and Interfaces for Stable Perovskite Solar Cells”
The photovoltaics industry has always been dominated by silicon-based solar cells. Originally expensive to make, production costs steadily dropped over time to the point where, now, there are practically no savings potentials left in the manufacturing processes for this technology. Accordingly, we need a new generation of cheap and efficient solar cells. Perovskite solar cells are especially promising. Their efficiency has increased very rapidly in recent years. The long-term stability of these cells is crucial for their economic viability, and yet this criterion is still barely studied. Antonio Abate’s goal is now to develop stable perovskite solar cells with an operating life exceeding 25 years.
"To achieve this goal, I want to improve our understanding of the optoelectronic mechanisms responsible for the degradation of material inside perovskite solar cells. I am researching both the fundamental principles and the processing of these solar cells in order to actively control the interfaces between the various layers", said the scientist. Antonio Abate is looking to cooperate with internationally leading research groups and industrial partners from the electronics industry to ensure the development of this technology is genuinely promoted – from materials and components to full PV systems.
About the “Helmholtz Young Investigators” programme
The research programme fosters highly qualified young researchers who completed their doctorate three to six years ago. The heads of the Young Investigator Groups receive support through a tailored training and mentoring programme. The aim of the programme is to strengthen the networking of Helmholtz centres and universities, too. More
- A simpler way to inorganic perovskite solar cellsInorganic perovskite solar cells made of CsPbI3 are stable over the long term and achieve good efficiencies. A team led by Prof. Antonio Abate has now analysed surfaces and interfaces of CsPbI3 films, produced under different conditions, at BESSY II. The results show that annealing in ambient air does not have an adverse effect on the optoelectronic properties of the semiconductor film, but actually results in fewer defects. This could further simplify the mass production of inorganic perovskite solar cells.
- BESSY II: How pulsed charging enhances the service time of batteriesAn improved charging protocol might help lithium-ion batteries to last much longer. Charging with a high-frequency pulsed current reduces ageing effects, an international team demonstrated. The study was led by Philipp Adelhelm (HZB and Humboldt University) in collaboration with teams from the Technical University of Berlin and Aalborg University in Denmark. Experiments at the X-ray source BESSY II were particularly revealing.
- Fuel Cells: Oxidation processes of phosphoric acid revealed by tender X-raysThe interactions between phosphoric acid and the platinum catalyst in high-temperature PEM fuel cells are more complex than previously assumed. Experiments at BESSY II with tender X-rays have decoded the multiple oxidation processes at the platinum-electrolyte interface. The results indicate that variations in humidity can influence some of these processes in order to increase the lifetime and efficiency of fuel cells.
