Reactive dc sputtered tio₂ electron transport layers for cadmium‐free sb₂se₃ solar cells

HIGHLIGHTS

• What: These previous reports, along with the present study, suggest the barrier to electron transport can be mediated by optimized TiO2 processing, provided sufficiently high electron conductivities and low interfacial defect densities can be obtained. The authors report a simple, scalable, reproducible method of preparing highly crystalline wide bandgap anataseTiO2 thin films for application as the ETL in Sb2 Se3 solar cells.
• Who: Christopher H. Don and collaborators from the JE. N. Swallow Department of Materials University of Oxford Parks Road, Oxford , PH, UK L. Bowen Department of Physics University of Durham Durham , LE, UK . . .
