The QEX10 Quantum Efficiency / Spectral Response / Incident Photon Conversion Efficiency Measurement System uses a xenon arc lamp source, monochromator, filters and reflective optics to provide stable monochromatic light to a photovoltaic test device. A broadband bias light also illuminates the test device to simulate end-use conditions. The system uses a detection circuit designed to maximize measurement speed and accuracy in solar cell research.
Multi - Junction Quantum Efficiency Measurements
The QEX10 includes a broad spectrum white bias light that can be used to bias most devices and provide almost any desired bias spectrum with the correct filtering. Using two or three bias lights, it is easier to get the correct bias light level for each junction. The correct bias lighting along with the correct voltage bias can allows the discerning scientist to make accurate measurements of each of the individual junctions in a multi-junction measurements.
High repeatability
The basic solar cell quantum efficiency measurement system wavelength range is 300 to 1100 nm. Repeatability is better than ±0.3 % in the 400-1000 nm range and better than ±0.6 % in the 300-400 nm and 1000-1100 nm ranges for p-n junction solar cells. The probe beam spectral bandwidth is approximately 5 nm (narrower or wider bandwidth can be obtained by adjusting the monochromator slits). The measurement interval is selectable and is set to 10 nm as a default. The graph on the left shows the relative difference between 5 measurements done on a single crystal Si sample and the average of those measurements.
