CELLO Measurements of CIGS and μcSi Solar Cells

摘要

The CELLO (solar cell local characterization) technique, which allows to measure all parameters of a solar cell locally with high spatial resolution, is applied for the first time for thin film solar cells based on Cu(In,Ga)Se_2 (CIGS) and micro-crystalline Si (μcSi). Results for local effective serial resistance, photocurrent and current/voltage at the working point will be presented, demonstrating the applicability of CELLO to thin film solar cells. Based on the measurements, quantitative predictions for the potential of these cells will be made.
