Zolix SCS600 양자효율 측정 시스템 SCS600 QE Measurement System

SCS600 solar cell quantum efficiency (QE/EQE) measurement system

SCS600 태양전지 양자효율 EQE 측정 시스템

Description

SCS600 is the second-generation product of the high-performance solar cell quantum efficiency / spectral response measurement system developed by Zolix. It can measure solar cells of various materials and is suitable for universities, research institutes and, R D and production quality management in enterprises. Compared with the first-generation product, the software is more user-friendly and easy to operate. Compatible with high-precision Keithley 2612B and 2636B digital source meters, which improves the data acquisition accuracy and bias test capability. Larger sample chamber and double doors make it easier to place and replace samples. In addition, Zolix provides customized services, so that the equipment can better meet customer needs. Main Functions: ■ EQE, IQE/ Spectral Response/ IPCE ■ Integrated JSC ■ It can measure the sample in glove box, vacuum chamber and other equipment ■ Wide spectral measurement range: 250nm – 1700nm ■ Light beam induced current measurement ■ CCD camera monitoring ■ Bias light test and bias voltage test ■ Provide AC and DC double data acquisition functions System Features High stability light source, good system repeatability Adopting the substitution method, light source stability is an important reason that affects the repeatability of the measurement results. Due to the different spectral response ranges of the detectors, the system provides high stability xenon lamp, tungsten lamp light source, their stability is higher than 99%, that ensure high repeatability and accuracy of measurement results. Monitoring CCD Clearly observe the light spot and precisely locate the sample. Professional Optical Design Total reflection optical path without aberration makes the measurement result more accurate. Converging the broadband light source in the transmission mode will cause aberration, as shown in the figure below, the spot size of different wavelengths is different, when testing small area detectors, there will be a large deviation.

SCS600은 Zolix가 개발한 2세대 고성능 태양전지 양자효율(QE)/분광 응답(SR) 측정 시스템입니다. 실리콘·GaAs·CIGS·CdTe·유기 태양전지 등 다양한 소재의 태양전지 측정이 가능하며, 최대 4인치 크기의 태양전지를 단일 또는 모듈 형태로 측정할 수 있습니다.

Specifications

The comparision of convergence light path imaging
High-intensity monochromatic light source makes the system signal-to-noise ratio higher

150W Xenon lamp output power curve
Adopting 150 W xenon lamp, the output power is larger than 6 mW/cm2 at 500 nm, over AM 1.5G spectral irradiance intensity.

1 mm circular spot, suitable to measure the samples larger than 1mm.

■ Fits standard glove box
■ External light source to avoid affecting the temperature in the glove box
■ 3D adjustable sample position
■ Dual door for easy sample change
■ Monitoring CCD observes the sample position

The LED light source wavelengths cover a wide spectral range from 365nm to 980nm, they are dedicated to measure the multiple solar cells. When measuring one of the cells, the bias lights are required to turn on the other cells, and the bias lights can't turn on the cell under test.
