Accessories It is a known fact that even the accurate testing requires a frequent and appropriate calibration of solar simulator light intensity. A secondary calibrated reference cell can enhance the good practise for daily process serving as guide if any abnormities resulting from deteriorating components. Spectral Filters Wheel Researchers today are faced with challenges on new and advanced materials for PV. The difference in Spectral Response between these new materials with reference cell make research job more difficult in getting correct cell efficiency. To counter this, we provide a solution using a Spectral Filters Wheel which holds multiple filters of different wavelength for user to measure the relative Spectral Response of the developed material. With this unique feature, user can now perform more accurate testing and calculations for the mismatching factor. Cell Chuck with Optional Thermal Table Customised Cell Chuck with probe bar is options available for user to load and unload the test Cells easily and also to minimize the contact resistance. Additional Thermal Plate can also be integrated into the cell chuck to have the cell in different temperature which is required in Cell Temperature coefficient measurement. NIST Traceable Spectroradiometer The combination of Xenon lamp and air mass 1.5G filter produces the characteristic Class A spectra. Even as Class A simulator its spectrum has a ±25% deviation from the specified percentages. And the spectral output of simulator is also changing through the life of the lamp. This spectroradiometer is used to analyze the spectral distribution of solar simulator. Spectral mismatch calculation can be achieved by using these data.
