• 태양전지(Photovoltaic Cells) 의 Solar Cell의 양자효율(IQE : Internal Quantum efficiency), Spectral Response, IPCE (Incident Photon to Charge Carrier Efficiency, External QE)등의 태양전지의 단파장에 대한 특성을 평가하기 위한 장비구성이다.

• Newport/Oriel에서는 사용자의 요구에 의한 구성이 가능하며, 사용하기 쉬운 Software 구현으로 아래와 같이
  나눌 수 있다.

• Simple QE/IPCE Measurement Kit
• External QE(EQE) & Internal QE(IQE) 동시 측정 시스템 Measurement Type : AC or DC, AC & DC 동시 적용 시스템
• Scan Wavelength : 300~100nm, 300~1800nm, 350~1800nm, 360~1800nm
• Optional Integrating Sphere, White Bias Source, Sample Holders with Temp controlled & Working TableWavelength dependent IV measurement

• QE Measurement의 기본 구성을 아래와 같다.

• Light Sources : 150W Xe, 300W Xe or 250W QTH Lamps(depends on scan wavelength)
• Monochraomtic Light Source : Monochromators with Focal Length 130mm or 260mm, 2 or 3 Gratings, Motorized Order Sorting Filter wheel/filters(2 or 3 filter depends on scan wavelength), Greater light throughput due to larger acceptance cone
• Chopper System with 2 Aperture Wheel for AC measurement
• Merlin Lock-in Amplifiers with 4CH Mulitplexer for AC measurement: Optical Power Meter and detectors for DC Measurement(needed dark box)
• Two Calibrated Si or sandwich Detectors with 50/50 Beam Splitter(IQE200 System)
• A Current Amplifier
• Data Gathering Part with Software
