3.2 Test theory

Firstly, the user gives instructions through the PC, and the
power supply charges the energy storage capacitor to provide the
energy required by the light source. When receiving the test signal
sent by the PC, the energy storage capacitor discharges to the xenon
lamp in the light source box through the light intensity control
circuit to generate constant irradiance, and then the electronic
load part synchronously collects the IV, temperature and other

parameters of the test module,

After processing, it is transmitted to the PC software. The software

processes the data through the algorithm, calculates the module
parameters, and finally draws the IV curve.

5.4 Calibration and correction
The equipment includes 5 kinds of correction,ISC, VOC, Pmax,

test temperature correction, irradiance correction and module area
correction. As shown in the figure below.
Calibration and correction operation figure
Calibration and correction is to set the necessary options

before the test, mainly including calibration, temperature setting
and irradiance setting. Each setting process is as follows:
Calibration
 Before starting the one click calibration, it is necessary to connect the
standard battery module as a reference to the equipment for a measurement

in order to obtain the actual measured value of the standard battery
module in the current test environment and input it into the measured
value column.
 Then you need to enter the nominal value on the nameplate label
of the standard battery module into the column of standard
value.
 After completing the above two steps, click one key to complete the

Sun Simulator
Instruction manual
correction.
 Note: due to the changes of the environment during the use of

the equipment, such as temperature, humidity, external light,
etc., in principle, the equipment needs to be corrected once
with standard battery modules after working for two hours to
ensure the accuracy of the test values.
Correction
The software default temperature is corrected to 25 ℃.
Set relative current temperature coefficient and relative
voltage temperature coefficient. The value of relative current
temperature coefficient corresponds to different solar module to
be tested. The corresponding relative current temperature
coefficient and relative voltage temperature coefficient must be
input. The relative current temperature coefficient and relative
voltage temperature coefficient reflect the sensitivity of the
internal current and voltage parameters of a single solar module
to temperature changes. The calculation formula is as follows:
Relative current temperature coefficient = absolute current
temperature coefficient / short circuit current
Relative voltage temperature coefficient = absolute voltage
temperature coefficient / open circuit voltage
The short-circuit current and open circuit voltage are the
values of the single chip to be tested under standard test
conditions. For example, when the short-circuit current of the solar
cell is 8A, the open circuit voltage is 0.6V, the absolute current
temperature coefficient is 0.0016 A / ℃, and the absolute voltage
temperature coefficient is
-0.0022 V / ℃, the relative current temperature coefficient and
relative voltage temperature coefficient are:
Relative current temperature coefficient =（0.0016 A/℃）/8A = 0.0002 /℃

Sun Simulator
Instruction manual
Relative voltage temperature coefficient =（-0.0022 V/℃）/0.6V =-0.0037 /℃
Irradiance correction options, no calibration and correction

options. If irradiance correction is checked, the test results will
be corrected according to the irradiance value after the test. If no
calibration and correction is checked, its none calibrated and
corrected data will be displayed after the test. If it is not
checked, it is the opposite.
The light intensity correction coefficient will affect the
displayed light intensity value on the screen, but will not really
change the light intensity.
The module area option is directly related to the change of EFF
value. When it is necessary to accurately obtain the EFF value of
the solar module, it is necessary to accurately measure the measured
effective area of the tested module and input it into the item of
module area.
5.5 Language change
In this option,the operator can select two type of language to

show. Operator can set the Chinese and English switching of the
operation interface. After the application,need to restart the
program to take effect. The interface is shown in the figure below.

serial number and docking with the code scanning gun of automatic
production line. It should be noted that when docking the automatic
production line, the number corresponding to the barcode length
needs to be input for different barcode lengths, and the barcode
prefix can be customized when outputting. The barcode prefix does
not occupy the barcode length. Example: when the bar code on the
next component to be tested is 22 bits long, and the tested bar code
needs to be prefixed with SCT. Then you can enter 22 in the barcode
length on the operation page as shown in the above figure, and enter
SCT automatically for barcode prefix.
Barcode label printing is supported, and the customer name can
be customized.
The database export directory can be customized. Whether this
function is enabled corresponds to whether access data export
function is required. The default state is off. After this function
is enabled, the data of each test will be automatically saved to the
selected directory. You need to pay attention to clearing disk space
regularly.
