PS-X10-100 Solar Cell I-V Test System

Data Sheets

 Solar cell, technical name Photovoltaic (PV), is the booming technology which converts sunlight (Including visible or ultra violet radiation) into electricity. Due to today’s growing demand for green energy, the solar cell is increasingly used in many areas, such as buildings, infrastructure and even mobile devices, as these industries become more eco-conscious. While PV devices absorb the solar irradiance and convert it into energy, the Keysight Technologies, Inc. I-V tester solution can measure the performance of various PV devices such as Silicon/ Thinfilm/ multi-junction in different power ranges. This could then be integrated with solar simulators for in-house tests. It is also suitable as a standalone for outdoor testing.

 Solution

Based on Keysight N3301A based Electrical Load mainframe, this integrated solution can greatly increase the solar cell’s I-V curve measure power by achieving 30A or higher efficiency and larger PV area. Further, it can apply to next generation with internal transient generator and high speed sampling digitizer which allows the sampling time to be even faster than 100 points within 10ms. With U2722A three channels 0.1nA resolution SMU, we utilize for reference cell Js measure as solar stability monitoring during I-V measurement. As the thermal effect may contribute to any test uncertainties, additional U2355A+U2802A (Or 34970A/ 34980A as alternative) can be used as multi-channel temperature data logging for coefficient correction after post analysis. The systematic rack stack is configured as turnkey solution for measurement. The benefit of the tester itself can be separated into parts for various test needs in advance.
