Biography
My research interests are new solar cell materials. I investigate both functional device properties and more fundamental small scale and short time scale properties and try to link these to obtain a better understanding of the devices. The techniques used for these investigations are X-ray photoelectron spectroscopy (XPS), photoelectrochemical measurements, laser pump probe spectroscopies, IR-spectroscopies and synchrotron based spectroscopies.
