Air photoemission system with scanning Kelvin probe – APS04-KP TechnologyThe APS04 systems measure the absolute work function of a material by Photoemission in Air, no vacuum required. With an excitation range of 3.3eV to over 7eV, the APS04 systems are capable of measuring the absolute Work Function of Metals and the full bands of Semicondcutors can be measured in one system, no other product can do this |

Ultra-violet/visible transmission/reflectance/absorption spectroscopy with integrating sphere – PerkinElmer Lambda 950The Lambda 950 soectrometer is a versatile instrument peration in the ultraviolet and visible spectral ranges. The spectrometer features a double-beam, double-monochromator, ratio-recording otpical system |

External Quantum Efficiency system – LOT SpeQuestApart from IV curves, the most important measurement on solar cells is that of the quantum efficiency. Our SpeQuest system is based on monochromatic light sources for measurements in the UV range |
 |
Current-voltage (IV) measurement station – LOT IV StationThe basis for IV curve measurements of solar cells is a temporally stable illumination spectrum close to that of the sun, provided by a solar simulator. If the solar simulator is combined with a contacting unit, a source meter as electronic load and corresponding controlling and analyzing software you have a complete IV curve measurement system |
