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.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
