PRECISE Digital Source Measure Meter Helps L-V Testing of Perovskite Solar Cells

Optimizing the Solar Cell Testing Process

From research and development to production of solar cells, each link has different testing requirements, mainly including maximum current IMAX and voltage VMAX, open circuit voltage Voc, short circuit current lsc, fill factor FF and conversion efficiency η, etc.

The power supply used in the traditional l-V test can only output voltage or current, and cannot absorb energy as a load, while the digital source measure meter (SMU) is a precision instrument that can provide a complete four-quadrant operation,

Combining the functions of current source, voltage source, ammeter, voltmeter and electronic load, it can independently measure the l-V characteristics of the device in all four measurement quadrants, greatly improving the test time and simplifying the overall test system design.

Since 2015, PRECISE has been committed to the research of digital source measure meters, and took the lead in realizing the localization of digital source measure meters in 2019, and successively launched high-precision digital source measure meters, plug-in source measure meters and other products, and cooperated with well-known manufacturers in the industry for Users create scientific research-level single-channel and multi-channel solar cell lV test systems to meet the test requirements of different power and precision.
