Determination of solar cell parameters by illuminated IV measurement is a standard characterisation technique used by many partners active in photovoltaics. The aim of this work is to carry out a cross check of different measurement set-ups used by different research partners of the EU CrystalClear project using industrialtype multicrystalline Si solar cells. In a first round robin a significant spread of all cell parameters (Voc, jsc, FF and efficiency) could be observed. After distribution of sister cells to selected cells calibrated at ISE CalLab, a second round robin was carried out. The spread in FF and jsc could be significantly reduced. Repeatability tests showed that by using a photo diode fluctuations of light intensity can be minimised and variations in jsc can be decreased down to 0.2 mA/cm2. Remaining systematic errors are control of cell temperature, contacting geometry, and use of appropriate reference cells.
