Product information:

Hgqe100 series solar cell QE / IPCE tester, also known as solar cell quantum efficiency tester and solar cell spectral response tester.

Hgqe100 series solar cell QE / IPCE tester can test the spectral response, spectral reflectivity, quantum efficiency or ipcemonic incident photo electron conversion efficiency, spectral transmissivity and AM1 Short circuit current density under 5g standard sun, etc.

Applicable solar cell type: professional and flexible different configurations, which can be applied to various types of solar cells.

Hgqe100 series solar cell QE / IPCE tester complies with iec60904-8 international standard. It is an indispensable and important tester for the research and production of solar cells.

Hgqe100 series solar cell QE / IPCE tester can simultaneously measure Iqe and EQE at the same point (internal and external quantum efficiency are measured at the same time), which is more professional, scientific and accurate.

High power and wide spectrum solar simulation light source ensures sufficient spectral range, stable radiation and high energy from 200nm to 2500nm; Current stability of power supply of light source: 0.05% @ 8.5a.

Automatic grating spectroscopic system with wavelength resolution of 0.1nm; Wavelength accuracy ± 0.2nm; Wavelength repeatability ± 0.1nm, equipped with automatic filter wheel to eliminate multi-level spectrum, combined with classical C-T structure to effectively filter stray light.

Adjustable test spot diameter of 38mm-1mm; Repeatability of short-circuit current density: < 1% monochromatic light spectral bandwidth < 5nm (adjustable), the default scanning step is 5nm (0.05nm10nm optional).

Data acquisition: the chopper phase lock is used to extract the signal and eliminate the noise. The chopper frequency adjustment range is 5-1000hz, and the sensitivity of the phase lock amplifier is 2nv.

Probe sample table, test sample size ≤ 156x156mm (larger size can be customized).

The software interface is humanized, that is, the simple operation of learning and learning.

In the system software, all instrument control parts are summarized into one interface, and all instrument parameter setting parts are summarized into one interface, so as to simplify the operation and control to the greatest extent and realize one key operation. The two measurement methods of flux method and uniform illumination method are compatible, and different formulas are used for data calculation and processing according to different measurement methods.

The instrument parameter settings can be saved as a file and exported uniformly, so as to realize the rapid restoration function and call the previously reserved parameter settings at any time. Parameter settings between different machines can also be called each other.

The chart and table files are automatically generated and displayed. The system software retains all the original data or exports them to documents in txt, xls and other formats. It is easy to do. The mainstream data processing software is called, and multiple groups of data are compared for subsequent analysis.

Automatic removal of gross error and automatic verification of system error, linear error, periodic error and t error.

Advanced optional features:

Semiconductor temperature control console: control the sample temperature range of 5-40 ℃

DC / AC mode optional chopper pulse illumination mode is compatible with steady-state continuous illumination mode, and one machine can be used for multiple purposes
