The EQE measurements have been acquired using a 100 W Xe arc lamp, a double monochromator, and a digital lock-in amplifier, integrated in the SPECLAB commercial setup from Fraunhofer ISE. The samples were placed on top of mc-Si solar cell used as reference, and the homogeneity of the DC layer for the different samples was also checked in order to obtain reproducible results. Scanning electronmicroscopy (SEM) images were obtained with a JEOL JSM-6300 electron microscope JEOL Ltd., Tokyo, Japan, with acceleration voltages of 20 and 10 kV. A qualitative energy dispersive X-ray (EDX) spectroscopy analysis of the surface was carried out with an Oxford In-
struments Microanalysis Group 6699 ATW. Atomic force microscopy (AFM) topographic images were taken in peak force tapping mode with a Digital Instruments from Bruker, Nanoscope V controller and a multimode microscope using etched RTESP silicon tips.
