Cu(In,Ga)Se2 Solar Cells: Device Stability Based on Chemical Flexibility

Year: 1999

Type: article

Abstract: Is “self-healing” the source of the stability of Cu(In, Ga)Se2-based solar modules? The proven remarkable stability and radiation hardness of Cu(In,Ga)Se2 (CIGS) solar cells stand in apparent contradiction to the fact that CIGS shows both short-range (metastable defect centers) and long-range (significant Cu migration) instabilities. The authors suggest that these instabilities may in fact be a prerequisite for CIGS's stability as they allow a degree of flexibility or “smartness” in accommodating externally imposed changes. Two self-healing cycles are proposed, in which copper species play a particularly important role.
