QE-R: IPCE Measurement

Key Features

• Compact and Flexible: All optical, mechanical, and electronic components—including dual lock-in amplifiers—are integrated into a single 60 × 60 × 60 cm main body. It saves a significant amount of laboratory space while maintaining flexibility for various types of solar cell test fixtures such as Si, thin film, tandem, CPV, CIGS, OPV, DSSC, and Perovskite solar cells.
• wavelength range: 300 ~ 1100 nm; 300~1800 nm; 300 ~ 2500 nm or customized.
• Provides data in QE (quantum efficiency), PV-EQE (external quantum efficiency), IPCE (incident photon-to-electron conversion efficiency), SR (spectral response), IQE (internal quantum efficiency), Reflectance.
• High Repeatability over 99.5%.
• Two independent lock-in amplifiers (each one is dual-phase) which monitor the optical power and measure the device signal simultaneously.
• Exclusive integrated computer-controlled signal switch can reduce costs for maintenance and consumables.
• Exclusive glovebox integration capability.
• Complies with ATSM E 1021-15, ASTM E948, IEC 60904-8, IEC 60904-7, IEC 60904-1.
• NIST-traceable SI traceable chain.
• Various and customized sample test fixtures.
