Advanced Science, EarlyView.An n‐type SnOx layer is constructed in situ on tin perovskite surfaces by converting surface‐enriched Sn4+ species through a one‐step SnCl2·2H2O treatment. This strategy enhances interfacial charge extraction and suppresses defect‐induced degradation, boosting the power conversion efficiency from 13.21% to 16.02% while maintaining negligible efficiency

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 ...

Advanced Energy Materials, EarlyView.An alcohol‐adduct‐mediated strategy is employed to stabilize tin isopropoxide for the formation of a homogeneous double electron transport layer (ETL) incorporating SnO2 nanoparticles (NPs). This double‐ETL exhibits improved optical and charge‐transport properties due to reduced defect density and better energy level alignment, resulting in high ...

E-ETL: Framework for Managing Evolving ETL Workflows [PDF]
Foundations of Computing and Decision Sciences, 2013 AbstractData warehouses integrate external data sources (EDSs), which very often change their data structures (schemas). In many cases, such changes cause an erroneous execution of an already deployed ETL workow. Structural changes of EDSs are frequent, therefore an automatic reparation of an ETL workow, after such changes, is of a high importance ...
