Dr. Onno Gabriel and co-authors were selected from more than 1,300 submissions for the TOP 20 publication of the conference.
From 14. to 18. September more than 2.500 experts on photovoltaics from all over the world met at the 31th EU PVSEC in Hamburg to discuss the latest developments and innovations. HZB was present at the conference with oral and poster presentations and in addition with an booth at the exibition. A joint publication by the Competence Centre for Photovoltaics (PVcomB) and Institute for Silicon Photovoltaics was chosen from 1,300 contributions under the best TOP 20 of the conference.
The European Photovoltaic Solar Energy Conference and Exhibition (EU PVSEC) is one of the largest international conferences for photovoltaic research, technologies and applications. It is regarded as the world’s leading platform for exchanges between the worlds of photovoltaic research and industry in the global photovoltaic solar industry sector. Over 2,500 experts from 77 countries met at the 31th EU PVSEC in Hamburg. More than half of the participants had been represented by research and development specialists and about 40 percent from the segment industry and engineering. 20 researchers from HZB have participated at the conference.
A HZB joint publication from PVcomB and Institute for Silicon Photovoltaics has been rated as one of the best current work in the field of photovoltaics submitted to the Conference. Dr. Onno Gabriel and co-authors were selected from more than 1,300 submissions for the TOP 20 of the 31th EU PVSEC with their publication "Crystalline Silicon on Glass: Interface Passivation and Its Impact on the Absorber Material Quality ". The authors of the 20 highest scored abstracts of the EU PVSEC 2015 are invited to submit a paper for publication in the renowned scientific journal Progress in Photovoltaics. The special edition will be available for free download for a year, a special feature of the not open access-publishing magazine.
Gabriel and his colleagues investigate the influence of new industrial processes to produce thin crystalline silicon layers directly on glass. This preparation method is developed at HZB for several years and promises high material and energy savings. The at HZB measured efficiency of 12.1% is currently the world record for this solar cell technology.
- Bright prospects for tin perovskite solar cellsPerovskite solar cells are widely regarded as the next generation photovoltaic technology. However, they are not yet stable enough in the long term for widespread commercial use. One reason for this is migrating ions, which cause degradation of the semiconducting material over time. A team from HZB and the University of Potsdam has now investigated the ion density in four different, widely used perovskite compounds and discovered significant differences. Tin perovskite semiconductors produced with an alternative solvent had a particular low ion density — only one tenth that of lead perovskite semiconductors. This suggests that tin-based perovskites could be used to make solar cells that are not only really environmentally friendly but also very stable.
- Synchrotron radiation sources: toolboxes for quantum technologiesSynchrotron radiation sources generate highly brilliant light pulses, ranging from infrared to hard X-rays, which can be used to gain deep insights into complex materials. An international team has now published an overview on synchrotron methods for the further development of quantum materials and technologies in the journal Advanced Functional Materials: Using concrete examples, they show how these unique tools can help to unlock the potential of quantum technologies such as quantum computing, overcome production barriers and pave the way for future breakthroughs.
