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.
- Lithium-sulphur batteries with lean electrolyte: problem areas clarifiedUsing a non-destructive method, a team at HZB investigated practical lithium-sulphur pouch cells with lean electrolyte for the first time. With operando neutron tomography, they could visualise in real-time how the liquid electrolyte distributes and wets the electrodes across multilayers during charging and discharging. These findings offer valuable insights into the cell failure mechanisms and are helpful to design compact Li-S batteries with a high energy density in formats relevant to industrial applications.
- Self assembling monolayer can improve lead-free perovskite solar cells tooTin perovskite solar cells are not only non-toxic, but also potentially more stable than lead-containing perovskite solar cells. However, they are also significantly less efficient. Now, an international team has succeeded in reducing losses in the lower contact layer of tin perovskite solar cells: The scienstists identified chemical compounds that self-assemble into a molecular layer that fits very well with the lattice structure of tin perovskites. On this monolayer, tin perovskite with excellent optoelectronic quality can be grown, which increases the performance of the solar cell.
- Berlin Science Award goes to Philipp AdelhelmBattery researcher Prof. Dr. Philipp Adelhelm has been awarded the 2024 Berlin Science Award. He is a professor at the Institute of Chemistry at Humboldt University in Berlin (HU) and heads a joint research group at HU and the Helmholtz Zentrum Berlin (HZB). The materials scientist and electrochemist is investigating sustainable batteries, which play a key role in the success of the energy transition. He is one of the leading international experts in the field of sodium-ion batteries.
