Solar cell module tester

Among all the performance characterization methods for solar photovoltaic devices, IV characteristic testing is undoubtedly the most intuitive, effective, and widely used method. By measuring the IV characteristic curve and further analyzing and processing the data, various physical properties of photovoltaic devices can be directly understood, including the efficiency of photoelectric conversion, fill factor, short-circuit circuit, open circuit voltage, etc. These data can provide reliable basis for the research, quality inspection, and application of photovoltaic devices.

This system supports Keithley24xx series source tables

3. Standard solar cells

The standard solar cell design and packaging meet the requirements of IEC60904-2 and can be used for irradiance calibration of various steady-state or transient solar simulators. The spectral response range of standard solar cells covers (300~1200) nm. The battery body includes a current signal output port and a temperature signal output port, both of which use the four wire method to output signals. The internal battery cell size is 20mm X 20mm, and the type can be selected from ordinary single crystal, polycrystalline, PERK, HIT, or provided by the customer themselves. A PT100 high-precision thermistor is embedded closely below the battery cell, which can accurately output the temperature signal of the battery cell. The signal output interface adopts the original LEMO interface and is equipped with two signal output lines (one end is a LEMO four wire male port, and the other end is four banana heads. If customized interfaces are needed, they can be specified in advance). Battery packaging glass can be customized according to customer needs
