European project for thin film Kesterite Solar cells has reached its goals

<span class="st">&nbsp;</span>

 

Eleven partners from different countries have joined forces in the EU-research project KESTCELLS from September 2012 until 31. August 2016. The mission was to train a new generation of experts and to increase the efficiencies of Kesterite solar cells. Now, at the end of the project, these goals have been perfectly reached.

Fourteen young scientists have become experts in the field and the cooperation managed to increase the efficiencies of Kesterite solar cells up to 11.8 %. This is even more than the 10 % threshold fixed as initial objective. HZB-scientists Iver Lauermann, Susan Schorr and Thomas Unold have been participating in the KESTCELLS-Project as Principal Investigators. The project was funded with 3.7 Million Euros by the European Union.

Background-Information:
In 2012 the European Commission identified a significant lack of academic institutions in Europe able to train new researchers in the field of thin based solar cells based on earth abundant materials. Being aware of this, the Research Executive Agency (REA) funded KESTCELLS with 3.7M€ to develop an ambitious program for training 14 researchers in 11 different institutions covering from Research Centers and Universities to Industries all around Europe.

For four years the partners of this ITN-network have worked with a double objective; in first place making a significant advance in the kesterite research of Thin-Film PV technologies. This field offers a set of advantages such as a low consumption of raw materials, development of highly automated and efficient manufacturing processes, low carbon footprint and better performances at elevated temperatures than the standard counterparts. Actually, it is expected that these technologies will lead PV research in the next years.

Secondly, the project has trained 12 PhD students and 2 experienced researchers recruited among more than three hundred candidates all around the world 

All in all, the project has allowed publishing more than fifty papers in peer review articles, and supported 6 Theses. From a scientific point of view, it has also made a significant step forward in the characterization of fundamental properties of kesterites that will allow understanding the main challenges on these materials and a contribution to a strategy to overcome them in the mid-term.

In fact, the design and development of new kesterite based solar cells with an efficiency of 11.8% has been achieved, which is beyond the 10% threshold fixed as initial objective of the project.  The project has contributed to the competitiveness of the European PV Industry, helping to increase the production of energy through renewable sources according to the 20/20/20 target established by the European Commission and the SET-Plan.

This project has received funding from the European Union’s Seventh Framework Programme for research, technological development and demonstration under grant agreement no [316488]. Sole responsibility lies with the authors and the European Commission is not responsible for any use that may be made of the information contained therein.

    A New Era in Catalysis: ASCEND Launch in Berlin, €30 Million in Funding
    On 11 June 2026, the Helmholtz-Zentrum Berlin (HZB) in Adlershof hosted the launch of ASCEND (Accelerated Solutions for Catalysis using Emerging Nanotechnology and Digital Innovation). The event took place in the presence of the Minister of Research, Dorothee Bär, President of the Helmholtz Association, Prof. Dr. Martin Keller, and President of the Max Planck Society, Prof. Dr. Patrick Cramer. Bringing together leading partners from industry and research, ASCEND is supported by BMFTR with €30 million in funding and officially started on 1 April 2026. The initiative aims to accelerate the discovery of next-generation catalysts and enable more sustainable chemical processes.

    X-ray analysis reveals overpainted fascist symbols
    Erich Mercker was a successful painter during the Nazi era and in the years that followed. After 1945, he covered up Nazi symbols in at least one of his paintings. With an interdisciplinary team, physicist Dr Ioanna Mantouvalou reports on this study in the Nature Journal Heritage Science.

    Magnon momentum microscopy: A new window into nanoscale spin-waves
    An international team lead by the Max Born Institute has developed a new type of momentum microscopy to image magnons — the quanta of collectively excited spins — directly in two-dimensional reciprocal space using soft X-rays. Measurements have taken place at BESSY II and PETRA III, first author ist the HZB physicist Steffen Wittrock. Owing to its remarkable sensitivity, simplicity, and access to nanometer-scale wavelengths, this novel technique establishes a powerful and versatile platform for exploring nonlinear magnon interactions, which are promising for future computing schemes.
