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.
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 .
