HZB scientist Dr. Antonio Abate has been awarded an ERC Starting Grant for his research project on perovskite solar cells. The ERC Starting Grant supports outstanding researchers in an early phase of their scientific careers with up to 1.5 million euros over five years and is considered one of the most important European awards.
Abate heads a Helmholtz Young Investigator Group at the HZB on organometallic perovskite solar cells since 2017. He was a member of Prof. Henry Snaith’s team at the University of Oxford when they achieved a step increase to eleven per cent in the efficiency level. Since then, perovskite solar cells have achieved efficiencies of more than twenty per cent. No other material class has shown such a rapid increase in photovoltaic effiency so far.
Abate is investigating processes both within the layer and at its interfaces. He intends to use the ERC Starting Grant to develop perovskite layers in which the environmentally harmful lead atoms can be replaced by less problematic elements.
He prevailed in a rigorous application selection process. 3,170 applications for the Starting Grants were received from all over Europe, of which 403 were approved. This represents a selection rate of about 13 percent.
“Our sincerest congratulations to Antonio Abate for this great success! In recent years, we at HZB have significantly intensified our efforts in the field of perovskite research and established several groups, because good research also needs critical mass in order to achieve synergy effects”, says Prof. Bernd Rech, acting Scientific Director of the HZB.
- BESSY II: Evaporated perovskites in tandem solar cells improvedPerovskite-silicon tandem solar cells achieve significantly higher efficiencies than silicon solar cells on their own. One particularly attractive method is co-evaporation of the perovskite precursor molecules on top of the silicon subcell. Scientists at HZB have analysed film growth on the nanoscale at BESSY II and found a new way to improve the quality of the perovskite layer: adding a thin seed layer of caesium chloride between the two sub-cells promotes uniform perovskite growth and suppresses the formation of undesired lead iodide at the interface.
- Hatice Mutlu appointed to the Helmholtz Institute HIPOLE in JenaProf. Dr Hatice Mutlu is the new professor of sustainable polymer chemistry at HIPOLE Jena, the Helmholtz Institute for Polymers in Energy Applications. On 17 August 2026, she visited the HZB campus in Berlin-Adlershof including the BESSY II lightsource and discussed future collaboration with researchers and the board of directors.
- Green hydrogen with PEC electrolysers: New insights into transport processesOne method of storing solar energy is to use PEC electrolysers to produce hydrogen. However, scaling up this technology remains challenging. Now, a team at the HZB Institute for Solar Fuels has used 2D fluorescence imaging and particle velocimetry to observe the movement of ions and dissolved gases within the electrolyte during electrolysis. These new insights may prove useful in the development of larger PEC electrolysers.
