Class A Performance
QuickSun® 800-Series solar simulators are always tested, certified and results reported exactly as specified in the applicable solar simulator standards and this is being proved by a globally recognized inspection body, SGS Fimko Ltd.
In order to comply with the Class AAA tolerances of the standard IEC 60904-09, ed. 2, proprietary optics has been developed for filtering the spectrum and improving irradiance non-uniformity. Since voltage, current and irradiance signals are recorded simultaneously, Short Term Instability (STI) is inherently 0% and in A class.
QuickSun 800-Series simulators are routinely applied to measure standard mono/polycrystalline silicon, or a-Si, CdTe and CIS/CIGS PV modules. The measurement of thin film materials only requires filtering of the monitor cell in order to comply with the spectral response of the material to be measured.
All QuickSun 800-Series simulators are equipped with two flash generators. This extends the length of the flash pulse and improves Long Term Instability (LTI). Capacitance Compensation (CAC) method allows testing of high capacitance PV materials.

QuickSun electronics records voltage, current and irradiance signals when voltage is swept from short circuit to open circuit. Simultaneously module temperature is measured either indirectly by ambient temperature measurement or by an IR sensor. Dark reverse IV characteristics can be recorded with an optional power source.

Every QuickSun simulator is thoroughly factory acceptance tested (FAT) before dispatching the system to the client’s site. The test results are included with the simulator documentation assisting the module manufacturers to convince their clients that modules are tested with a true Class AAA simulator.
Non-uniformity is measured by recording the short circuit current distribution of a laminated c-Si cell over specified test area. The same test can be easily reproduced at client’s site by using the test sensor and QuickSun software tools provided with the simulator.
Spectrum of every simulator is recorded and compared to comply with the Class A tolerances as specified in IEC 60904-9, ed. 2
Voltage, current and temperature measurement accuracies are calibrated and verified to comply with IEC904-1 ed. 2 specifications. Irradiance measurement accuracy is factory calibrated but final calibration is performed on-site by applying client’s certified reference modules.
QuickSun software is designed to provide flexibility for different end-users, from fully automated large scale production lines to smaller factories and research institutes. It combines a diverse range of options for control and data handling to ease in use and simplicity. Full remote control of the software is possible through a TCP interface, and measurement data is conveniently transferred to an external database using an ODBC interface.
Classification of measurements based on all key performance parameters is readily available. QuickSun also analyses curve derivatives for shunt and series resistance evaluation, measures series resistance according to IEC 60891, and has easy-to-use features for irradiance non-uniformity measurement.

800-Series simulators can be installed either horizontally or vertically and instructions for constructing a corresponding flash tunnel or tower are supplied with the simulators.
Flash tunnel gives easier access to the flash head e.g. for changing the flash tube but takes more factory space. A test surface with fixed test sensor positions covering the nominal test area of each simulator is an essential part in order to perform fluent and reproducible irradiance nonuniformity measurements.
EL imaging option is available with two integrated 8.3 MP CCD cameras. This results in about 500 μm pixel resolution and enables visual detection of faults like micro cracks. Typical exposure time is 5–20 seconds and 850 W power source provides up to 14 A to 72 cells c-Si modules.
Also instrumentation for Electrical Safety Testing option is available including manual frame contacting. True leakage current and insulation resistance are evaluated simultaneously with nA scale measurement sensitivity which confirms also reliable frame contacting.
