Title: Research Level I-V and QE Measurements

A summary of key points related to research-level measurements of current-voltage (I-V) and quantum efficiency (QE) for various types of photovoltaic cells include the following: (1) Compare measurements with another trusted laboratory often enough to see the random error; (2) Have a calibration lab calibrate your research cell; (3) Document potential metastabilities and sensitivity to premeasurement conditions; (4) Measure the 1-sun spectral responsivity with a bias light level of 0.37 times the expected 1-sun short-current current; and (5) Be aware of bias rate artifacts in I-V and QE.
