CALIBRATION OF SOLAR SIMULATORS
FYTRONIX is accredited to perform solar simulator classification measurements at Standard Test Conditions (STC) according to ASTM E9712, IEC60904 and JISC 8912. These measurements include the solar simulator's AAA classification.
AAA classification of Solar Simulator
a. Spectral Matching
b. Homogeneity measurement
c. Instability of irradiance
Short-term (STI) and long-term(LTI) instability.
All measurements can be traced to SI units and performance parameters (Spectral coherence, homogeneity, radiative instability)are provided with uncertainty estimates validated through international comparisons.
CALIBRATIONTESTS OF CURRENT-VOLTAGE BOARDS
FYTRONIX is accredited to measure current-voltage (I-V curve) under Standard Test Conditions (STC) according to IEC 60904 for a wide variety of devices. The current-voltage measurements of current-voltage boards are traceable to SI units and performance parameters (i.e. PMAX, OC, ISC, η) are supplied with uncertainty estimates validated through international comparisons.
Upon completion of the test, an ISO/IEC 17025 accredited calibration certificate is issued. Our detailed current-voltage board evaluation in the factory allows module manufacturers to minimize their rating tolerances.
CURRENT-VOLTAGE. TESTS OF PHOTOVOLTAIC DEVICES
FYTRONIX is accredited to measure current-voltage (I-V curve) under. Standard Test Conditions (STC) according to ASTM E972, IEC60904 and JISC 8912 for a wide variety of devices. These measurements range from 10mm x10mm research scale devices to 2.5m x 2.5m commercial modules. The solar cells are measured with a steady-state dual light source solar simulator and modules are measured with solar simulator. Section measurement is performed to minimize the effects of hysteresis. All measurements are traceable to SI units and performance parameters (i.e. Pmax, Voc, Isc, η) are supplied with uncertaintyestimates validated through international comparisons.
Upon completion of the test, an ISO/IEC 17025accredited calibrationcertificate is issued.
Our detailed simulator evaluation in the factory allows module manufacturers to minimize their rating tolerances.
CALIBRATIONOF REFERENCE SOLAR CELLS
Our accredited services also include the calibration of pyranometers and reference cells used for irradiance measurements. Both are calibrated in our steady state solar simulator with excellent long and short term irradiance stability, homogeneity and spectral matching. Mismatch factor correction is applied to PVdevices, resulting in a minimal increase in measurement uncertainty above thereference standard used for calibration.
We provide comprehensive qualification of solar simulators for use inthe production of PV modules and issue recognized certificates to simulator manufacturers. Our experts serve many customers around the world, providing validation, classification and certification as well as reliable testing and precise results. On-line measurements also allow PV module manufacturers tooptimize existing systems to increase in-line power control accuracy.
REFERENCESOLAR CELL CALIBRATION
All measurements are performed under standard conditions (SRC) with 25 oC temperature, 1 SUN (1000 W/m2) total irradiance and AM1.5G spectral irradiance (IEC 60904-3). Upon completion of the test, an ISO/IEC 17025 accredited calibration certificate is issued. The certificate includes:
• Measured total area of the device
• EQE and IV curves for the device
• Spectral irradiance spectrum of the solar simulator
• Spectral response of the reference solar cell
• Expanded uncertainties
• Electrical performance parameters of the solar cell
• Short Circuit Current (Isc)
• Open Circuit Voltage (Voc)
• Current at Max Power (Imax)
• Voltage at Max Power (Vmax)
• Max Power (Pmax)
• Spectral Correction (M)
• Fill Factor (FF)
The laboratory welcomes requests for prototype PV device performance measurement or PV reference cell calibrations.
An integral part of solar simulator calibration and solar cell I-V characterization, the FYTRONIX Reference cell consists of a reading device and a 2 x 2 cm caliber solar cell made of monocrystalline silicon. The cell is also equipped with an assembledthermocouple according to IEC 60904-2. The certification is accredited by NAC to the ISO-17025 standard and is traceable to both the National RenewableEnergy Laboratory (NREL) and the International System of Units (SI). solar simulator irradiance in "solar" units; 1000 W/m2 equals 1000 W/m2 at25 °C and Air mass 1.5Global Reference
