Beyond the Gold Standard: Towards Industrially Viable Electrodes for Durable Perovskite Solar Cells
Advanced Energy Materials, EarlyView.Transparent and opaque electrode materials are mapped by raw material cost per 1 m2 electrode area and retained median device efficiency after heat–light ageing. FTO offers a lower‐cost and more stable alternative to ITO, while Cr/Al provides the lowest‐cost rear electrode investigated with Au‐like stability and substantially improved durability ...
