Tektronix TSP-2000-SOLAR multi-group solar cell IV test system solution for semiconductor devices

Solar cells or photovoltaic PV cells are devices that absorb photons from a light source and then release electrons, which can cause current to flow when the solar cell is connected to a load. Solar cell researchers and manufacturers strive to achieve the highest possible efficiency with minimal losses. Therefore, the electrical properties of solar cells and photovoltaic materials become part of the research, development and manufacturing process. IV characterization of solar cells is crucial to derive important parameters regarding their performance, including maximum current Imax and voltage Vmax, open-circuit voltage Voc, short-circuit current Isc, and efficiency eta.

More and more scientific researchers are investing in the research of solar cells, among which solar cells such as organic thin film material batteries, gallium arsenide material batteries, and dye-sensitized materials have become research hot spots. The photoelectric characteristics of solar cells include voltammetry IV characteristics, spectral response SR characteristics, and quantum efficiency QE characteristics. Solar cell IV characteristics testing is a key step in evaluating solar cell parameters.

In order to accurately complete the IV characteristic test of solar cells, researchers need to use a solar simulator light source to irradiate the sample within a certain distance, and then use precision electrical instruments to measure the IV characteristic curve to obtain the battery parameters.

How to accurately, simply and quickly implement the IV characteristic test of batteries is the main problem faced by current scientific researchers.

Program features

The multi-group solar cell IV test system solution uses an international standard AAA level solar simulator to replace traditional halogen lamps, xenon lamps and other light sources, which can completely simulate the solar spectrum of space and ground, and solve the matching problem of incident spectrum of solar cells in laboratory testing; and The battery IV characteristic test instrument uses Keithley's latest high-precision source measurement unit SMU, which has ultra-wide photocurrent and dark current measurement capabilities from 100fA to 10A, and can cover most battery power tests. Combined with a precision multi-channel switch and a customized fixture based on the shape of the customer's battery electrode, it can achieve continuous IV testing of the largest number of battery cells, greatly improving test accuracy, repeatability and efficiency.

The entire system can test the IV characteristics of each battery unit independently or sequentially through CycleStar software, displaying the IV characteristic curve and parameters such as Isc, Voc, Pmax, FF, eta and battery surface temperature; the test results of each battery unit can be saved in an EXCEL In the file, statistical analysis of the battery surface uniformity distribution can be performed.

· Simple testing: simply connect the sample to the fixture, turn on the solar simulator, and run the software.

· Fast testing speed: Automatically switch between multiple battery groups for measurement, no need to connect each time.

· High test accuracy and good repeatability: current 100fA ~ 10A, voltage -200V ~ 200V.

· The test can be upgraded: the simulator can be replaced with a high-power simulator, the SMU uses a higher-power two-quadrant source measurement unit, and the switch host can replace the multi-channel switch to implement multi-channel testing.

· Expandable functions: Combined with the probe station, it can test LED, OLED, MOSFET and other devices.
