CIMPS-QE/IPCE -UV Photovoltaic/Photoelectrochemical System
Zahner's CIMPS is a highly dynamic LED-based system with an active light feedback loop that ensures a controlled and constant light intensity during the photoelectrochemical or photovoltaic measurements. Fast light sources enable dynamic photoelectrochemical measurements like IMPS/IMVS. The robust control of light intensity allows accurate IMPS/IMVS measurements, giving the system its iconic name "controlled intensity-modulated photo spectroscopy (CIMPS)".
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.
