Solar cell testing solution based on Keithley four-quadrant SMU source

Solar cells, also known as "solar chips" or "photovoltaic cells", are optoelectronic semiconductor sheets that use sunlight to directly generate electricity. As long as it is illuminated by light that meets certain illumination conditions, it can instantly output voltage and generate current if there is a loop. In physics, it is called solar photovoltaic (photovoltaic, abbreviated as PV), or photovoltaic for short. Solar cells are devices that directly convert light energy into electrical energy through the photoelectric effect or photochemical effect.

From R&D to production of solar cells, each link has different testing requirements. Keithley's new solution can meet users' different power and accuracy requirements, save R&D and production time, and greatly improve work efficiency.

Facing the diverse testing applications of solar cells from R&D to manufacturing, Keithley has launched a new solar cell testing solution. With the four-quadrant SMU source meter as the core, coupled with the ACS Basic special software, it is designed to help users free themselves from complex programming and save time for the next scientific research breakthrough. At the same time, Tao Jianzhong provides different selection configurations to meet users’ testing needs of different power and accuracy.

The advantages of Keithley’s solar cell testing solutions are:

1. No programming required

ACS Basic software contains special modules for solar cell testing, which saves measurement time and improves testing efficiency. ACS Basic is a semiconductor parameter testing software platform. It is mainly used for characteristic analysis of packaged components and discrete devices. It supports Keithley 2400 series, 2600B series and high-power 2650A series SMU source meters. Its built-in solar cell module can automatically calculate typical parameters of solar cells, such as ISC (short circuit cell), VOC (open circuit voltage), Pmax (maximum power point), FF (fill factor), etc. Users can obtain parameters directly without programming. As a result, measurement development time is saved.

2. Flexible configuration

Meet the different power requirements for solar cell and solar panel testing: The SMU in the SolarCell-24 series is Keithley's new generation touch screen single-channel SMU, with a friendly interface and easy to use. The front panel can directly display iv curves and data. SolarCell- The SMUs in the 26 series are available in single and double channels, with 10A Pulse test function. The unique TSP technology increases test throughput and improves test speed; at the same time, for the testing needs of high-power solar panels and battery packs, Keithley can Provide ±20A DC/±50A Pulse and ±3KV solutions.
