CIMPS-QE/IPCE Highlights:
CIMPS-QE/IPCE is an extended CIMPS system with the capability to measure quantum efficiency (QE) or incident photon to current efficiency (IPCE). The CIMPS-QE/IPCE extension consists of an easily mountable and portable tuneable light source (TLS). The TLS contains dynamic LEDs, a monochromator and a feedback control which allow accurate light illumination during the measurements without any warm-up time.
Multiple LEDs in the TLS provide higher light intensity across the broad wavelength range and longer operational lifetime as compared to any traditional Xe-lamp. This high light intensity is crucial for IPCE measurements on DSSC, perovskites or organic solar cells or photoelectrodes.
Like the modular LEDs used in the CIMPS system, the TLS is also able to carry out sine-wave modulation for IPCE measurements and does not require a mechanical chopper. During IPCE measurements, a special indicator is also provided which indicates if the measurement parameters are optimum for IPCE measurement or not. Further information about IPCE measurement is provided in our application note CIMPS-IPCE.
Zahner offers TLS with two different wavelength ranges.
- TLS03: 365 nm – 1020 nm
- TLS03/UV: 290 nm – 1020 nm (with UV extension)
