Abstract
En 中文
• Advanced electron microscopy resolves nanoscale structure/chemistry in 10-year weathered HIT modules. • ∼1.5 nm Oxygen-rich SiOx layers quantified at In2O3/a-Si:H interface in control & weathered cells. • No statistical change in SiOx interlayer thicknesses or a-Si:H morphology. • Subtle interfacial changes may relate to module electrical loss with aging.
