Abstract
The photoinduced open-circuit voltage decay technique was
used to investigate the minority canier lifetime in crystalline and
polycrystalline silicon solar cells. Tlus convenient investigation
tecluuque allows a fast detennination of the minOlity canier lifetime
in senUconductor matelials and is an impOltant technique to predict
the solar cell perfOlmance. The decay curves were obtained with a xenon
stroboscope lanlp and Nd:YAG laser and Nitrogen laser pulses as an
excitation source
