ISFH-CalTeC is “designated test centre” for the confirmation of solar cell world records

16.01.2018

The Solar Cells Laboratory of the Calibration and Test Center (CalTeC) at the Institute for Solar Energy Research (ISFH) is now on the list of “designated test centres” that confirm solar cell efficiency world-records for the “Solar cell efficiency tables”. These efficiency tables are one of the most important references for the technological development of solar cells.

The efficiency tables published in the international journal “Progress in Photovoltaics” (Wiley) list the currently highest independently confirmed efficiencies for solar cells and modules every six months.

The “Solar cell efficiency tables” are one of the most important references for the technological development of solar cells. The 51st edition, published on December 14, 2017, lists seven so-called “designated test centres”, including ISFH-CalTeC.

These test centres have the required measuring accuracy and international comparability for the determination of solar cell efficiency world records.

The inclusion of the ISFH-CalTeC Solar Cells Laboratory in the list of recognized test centres follows the successful accreditation for the calibration of solar cells according to DIN EN ISO/IEC 17025 by the German Accreditation Body (DAkkS) in 2016.

The accreditation covers the measurement of the spectral responsivity (SR) and the determination of the characteristic solar cell parameters (Isc, Voc, FF and η) of the current-voltage curve (IV-curve) of solar cells under standard test conditions as defined in the IEC60904 standards.

By default, all parameters are specified with their accompanied uncertainty. For traceability to SI units, references that are regularly calibrated at the Physikalisch-Technische Bundesanstalt (PTB) in Brunswick, the national metrology institute in Germany, are used for all measurements.

The calibration service of the ISFH CalTeC focuses on the measurement of wafer-based silicon solar cells from laboratory scale up to industrial formats.

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
