Dear Scientist,
as a part of the Oak Ridge National Laboratory Users Week the Center for Nanophase Materials Sciences organizes the 2010 CNMS user meeting. A photovoltaic workshop will take place from September 15th to 16th. We kindly invite you to participate in the demonstration and practical course

Impedance and Photo-Electrochemical Techniques in Renewable Energy Research
Sept. 15th - 16th, 2010 at CNMS User Meeting 2010, Oakridge

held by Zahner Messtechnik in the framework of this meeting on September 16th. Charly Schiller from Zahner will introduce the participants into the basics of dynamic transfer function analysis applied in electrochemical and photovoltaic power generation. Practical experiments will be performed on DSSC (dye sensitized metal oxide solar cells), OSC (polymer organic solar cells ) and silicon solar cells.Intensity Modulated Photocurrent Spectroscopy IMPS and Intensity Modulated photoVoltage Spectroscopy IMVS for the determination of photoelectron diffusion and lifetime constants will be demonstrated. The principle of Zahner’s proprietary high accuracy Controlled Intensity Modulated Photo Spectroscopy CIMPS/CIMVS procedure will be explained. Besides, the following standard SC characterization methods / parameter determination will be shown: fill factor, efficiency, maximum power/voltage/current, spectral resolved Incident Photon Conversion Efficiency IPCE, charge extraction after L.M. Peter. The course is broadened by absorption spectroscopy experiments on the electro-chromic behaviour of organic polymer films and by emission spectroscopy of OLED devices. Furthermore, Zahner will present the brand-new PAD4 extension, which allows the parallel acquisition of up to 17 impedance channels e.g. of fuel cell stacks or batteries. An experiment with a battery array will demonstrate this unique feature.
