Advanced Science, EarlyView.Depression is increasingly recognized as a risk factor for chronic diseases, yet its biological impact on cancer remains unclear. Using data from more than 490 000 participants across three international cohorts, we show that depression significantly increases the risk of liver cancer.

Dry‑Contact Trimming for All‑Perovskite Tandem Solar Cells via Solid‑Solution Homogenization
Advanced Energy Materials, EarlyView.Narrow‐bandgap Sn–Pb perovskites are promising bottom absorbers for all‐perovskite tandems but suffer from Sn‐rich surfaces and depth‐dependent lattice/compositional inhomogeneity. Layered‐perovskite‐assisted dry‐contact trimming removes Sn‐rich surface species and reconfigures the Sn–Pb absorber, enabling efficient charge collection, reduced voltage ...

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 ...
