The surface photovoltage spectroscopy modules are the perfect all-in-one solution for in-depth studies of light sensitive materials such as organic semiconductors, solar cells or light sensitive dyes. The modules offer a comprehensive range of measurement modes including DC and AC surface photovoltage studies utilising the built-in optical chopper. Total digital control of all parameters including light intensity and wavelength (400 - 700 nm: SPS030 or 400 - 1000 nm: SPS040) gives the opportunity to investigate and characterise the surface photovoltage and surface photovoltage spectroscopy properties of samples. The latest materials and applications highlighted in published papers includes, gold films, perovskite solar cells, titanium dioxide nanotubes, dye sensitised solar cells, hybrid organic/inorganic photocathodes and tungsten trioxide. Download the product brochure for more information on the Surface Photovoltage range, including technical specifications, example measurements and add-on options. - SPS030 - SPS040 - SPV020
