SPEED LIMITATION IN SPATIAL UNIFORMITY MEASUREMENTS OF SOLAR CELLS USING A BEAM PROJECTOR

Jae-Keun Yoo, Seung Kwan Kim, Seung-Nam Park

Abstract

We examined the potential sources that limit the measurement speed in our recently demonstrated apparatus to inspect spatial uniformity of solar cells using a beam projector. Using a repeated trigger measurement function of the source-meter and fast moving video images, we showed that the measurement speed was mainly limited by the video signal modulation. As a result, reliable measurements of short circuit current with about 30 ms per position could be achieved.
