Prize for young scientists in photovoltaics awarded to Dr. Bianca Lim (ISFH)

26.09.2012
Dr. Bianca Lim from the Institute for Solar Energy Research (ISFH) in Hamelin, Germany, is this year’s winner of the SolarWorld Junior Einstein Award.
The 30-year-old physicist won over the jury with her work on boron-silicon compounds in silicon solar cells. The compounds are the main reason for the efficiency limit of highly efficient solar cells. Although the phenomenon has been known for a few years, the causes were not yet fully explained.

For her dissertation, Dr. Lim studied the behavior of boron-oxygen compounds and a procedure for moving them to a location where they do not cause damage. She is following in the scientific footsteps of the first winner of the SolarWorld Junior Einstein Award, Axel Herguth from the University of Konstanz, Germany. One very important conclusion of Lim’s work was that boron-oxygen compounds behave differently in lower-cost silicon than had been expected. Additionally, she explored ways in which to eliminate the damaging effect of boron-oxygen compounds. As a result of her experiments, Dr. Lim was able to develop a new model to explain the three-way relationship between boron, oxygen and silicon resulting during the formation and separation of the compounds.

“The efficiency of solar cells will in the future be even more strongly linked to defects and impurities in the silicon. Preventing these defects or moving them to locations where they do not cause damage can greatly increase the potential of the efficiency,” said Dr. Lim’s doctoral advisor Prof. Dr. Jan Schmidt. “Dr. Bianca Lim set herself apart from the numerous other applicants due to her scientifically grounded work that is also highly relevant for solar cell manufacturing,” said jury member Dr. Gunter Erfurt, explaining the decision.

Dr. Bianca Lim is the first female winner in the seven-year history of the renowned award for up-and-coming scientists in the field of photovoltaics. Twelve applicants in all made it to the final round of this year’s scientific competition. The jury came to its decision following a day of presentations by all of the finalists in Freiberg in the German state of Saxony, where SolarWorld AG’s largest production facility and the headquarters of its SolarWorld Innovations research company are located.

Lim completed a physics degree at the Freie Universität Berlin and wrote her diploma thesis at the former Hahn-Meitner-Institut (now the Helmholtz-Zentrum) in Berlin. Already while writing her thesis, she dedicated herself to renewable energies and carried out research on solar cells with ultra-thin absorber films made of indium sulfide and lead sulfide. After finishing her studies in Berlin, Lim began as a doctoral student at ISFH in Hamelin and completed her Ph.D. in 2012 at the Gottlieb-Wilhelm-Leibniz University in Hanover.

About the SolarWorld Junior Einstein Award: Since 2006 SolarWorld AG has presented this award to young scientists whose academic work has demonstrated excellence in photovoltaics or a related field. Graduates of a university or university of applied sciences program in electrical engineering, mechanical engineering, renewable energy, engineering, chemistry, physics or process engineering are eligible to apply.

About ISFH: The Institute for Solar Energy Research is a private branch of the Leibniz University in Hanover and a leader in the development of methods for the production of highly efficient silicon solar cells. The ISFH presently employs around 160 staff, just under one third of which are students and doctoral candidates.

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
