We are no longer accepting new orders for the QEX7 Solar Cell Spectral Response/IPCE/Quantum Efficiency Measurement System.
Please see the QEX10 Solar Cell Quantum Efficiency Measurement System for the culmination of PVM over a dozen years experience in solar cell Spectral Response/IPCE/Quantum Efficiency Measurements.
Since the introduction of the QEX10 in June of 2010, we have shipped many units and received great customer feedback. Based on that feedback and in order to best serve our customers, we are now offering the QEX10 and QEW7 systems. PVM will continue support for the many QEX7 systems that are in use in photovoltaics development laboratories and manufacturing facilities around the world.
For users familiar with use and operation of the QEX7, the QEX10 will look familiar. The software has been modified to make operation of the system easier while keeping key components in similar locations to make it easy for users of the QEX7 to transition to the QEX10.
For users that have enjoyed the simple mounting of samples on the various test fixtures used with the QEX7, the QEX10 offers more room to work and even easier, more flexible mounting options Switching between Reflectance and EQE modes now takes only a few seconds and no optical realignment.
System maintenance has been simplified with easier access to consumable parts and reduction in the number of tools needed
The QEX10 has a smaller footprint than the QEX7 to conserve laboratory space.
QEX7 description
PVM solar cell QE systems can measure the spectral response of a wide variety of photovoltaic devices, including p-n junction and dye-nanocrystalline solar cells (DSSCs).
All QEX7 solar cell QE systems include a xenon light source, monochromator, filters, and reflective optics to provide monochromatic light to a photovoltaic device while a broadband bias light illuminates the test device to simulate end-use conditions. A computer interfaces with the monochromator, signal conditioning equipment, and digital signal processing equipment; interprets signals; maintains calibration information; saves test data; and produces test reports. Different models include different features and can be configured with different options.
Basic System Features
Dual grating monochromator with computer control
Filter wheel with order-sorting and stray light attenuation filters
Calibrated reference photodiode
Line filter for wavelength calibration verification
White bias light source
Simultaneous measurement of device response and light intensity
