Solar Battery Volt-Ampere Test

Among all the characteristic characterization methods of solar photovoltaic devices, I-V characteristic test is intuitive, effective and widely used.

By measuring the I-V characteristic curve and further data processing and analysis, the main physical properties of photovoltaic devices can be obtained, including photoelectric conversion efficiency, short-circuit current, open-circuit voltage and fill factor.

These data can be used as a reliable basis for the research, quality inspection and application of photovoltaic devices.

Sample Requirements

Solar cells: Can be crystalline silicon, amorphous silicon, organic polymer, or other types of solar cells.
Before testing, it is necessary to ensure that the surface of the sample is clean and the solar cell has been fully illuminated. In addition, it is also necessary to set appropriate test parameters according to test requirements, such as light intensity, load resistance or constant current value, etc.

Application

For the research, quality inspection and application of photovoltaic devices
Test the volt-ampere characteristic curve, fill factor (FF), photoelectric conversion efficiency, open circuit voltage, and short circuit current.
