Abstract
Using a 217 Hz focal plane array (FFA) thermocamera attached to two paralle l-running DSP frame grabber boards in a PC, a highly sensitive lock-in ther mography system has been built, enabling the detection of periodic surface temperature oscillations below 10 muK (r.m.s). This system has been used to investigate edge leakage currents in silicon solar cells after laser scrib ing and cleavage. (C) 2001 Elsevier Science B.V. All rights reserved.
