PVcomB-25 paper awards for two HZB-Contributions
On stage for the PVSEC-25 Paper Awards. Jan-Peter Bäcker (1. on left side) and Marc Daniel Heinemann (5. on left side).
At the 25th International Photovoltaic Science & Engineering Conference (PVSEC) two papers from the HZB-Institute PVcomB have been awarded: Jan-Peter Bäcker and Marc Daniel Heinemann received the PVSEC-25 Paper Award for their research on chalcogenide solar cells (CIGS). The PVSEC was held from 15. to 20. November in Busan, Korea.
Jan-Peter Bäcker and his co-authors presented their research on phase separation in Copper-Indium-Gallium precursor thin films for sequentially processed Cu(In,Ga)Se2 solar cells". Marc Daniel Heinemann and his co-authors reported on results on CIGS solarcells in „superstrate“-configurations.

- New contact material boosts the efficiency of perovskite solar cellsA newly developed material for the electron contact improves the efficiency of single perovskite solar cells and perovskite/silicon tandem solar cells. The new material is based on a carborane molecule. It offers several advantages over the standard material C60, as shown by the study led by Steve Albrecht’s team. The new material has since been patented and is already commercially available.
- Precision interface chemistry pushes perovskite solar cells beyond 26% efficiencyAn international research collaboration has developed a new molecular strategy for controlling one of the most critical interfaces in perovskite solar cells. The resulting solar cells reached a power conversion efficiency of 26.19% in the n i p architecture, together with strong operational stability under prolonged illumination and elevated temperature. The results have been published in the Journal of the American Chemical Society.
- Perovskite triple-junction solar cells: Even more efficient with GO/SAM bilayersPerovskite semiconductors efficiently convert sunlight into electrical energy; they are also inexpensive and extremely lightweight. A team at HZB has developed a triple-junction solar cell comprising different perovskite semiconductors, with a novel bilayer of graphene oxide (GO) and a self-assembled monolayer (SAM) as the hole conductor. This bilayer significantly increases both efficiency and long-term stability. The efficiency of the novel perovskite triple-junction solar cell is 27.3% and shows hardly any decline even after more than 770 hours of operation. The study has been published in the renowned journal Joule.
