Figure 1 from “Operando Characterizations of Light-Induced Junction Evolution in Perovskite Solar Cells” by Chuanxiao Xiao et al. Experiment schematic. KPFM scans on the cleaved cross-sectional surface. Ultrafast spectroscopy measurements were in both TA and TR setups. NANOSENSORS Platinum-Iridium coated PointProbe Plus PPP-EFM AFM probes were used for the Kelvin Probe Force Microscopy.

Light-induced performance changes in metal halide perovskite solar cells (PSCs) have been studied intensively over the last decade, but little is known about the variation… Read More »Operando Characterizations of Light-Induced Junction Evolution in Perovskite Solar Cells

Figure 4 from by “Photoinduced Charge Transfer and Trapping on Single Gold Metal Nanoparticles on TiO2” Monica Luna et al : Topography (top) and VCPD (bottom) images of a 3 nm diameter Au NP on bare TiO2(110) (a) in the dark and (b) under UV illumination. VCPD profiles are shown at the bottom. Color scale in topography: (a) 3.6 nm and (b) 4 nm. A CPD image of a larger sample area can be found in the Supporting Information (Figure S10). NANOSENSORS tip view conductive AdvancedTEC ATEC-EFM AFM probes were used.

Numerous advances of societal significance, such as CO2 conversion to fuels, hydrogen production by water splitting, and new materials with self-cleaning and antifogging properties, are… Read More »Photoinduced Charge Transfer and Trapping on Single Gold Metal Nanoparticles on TiO2
