- Abstract
- In2O3 micro-cubes were fabricated via chemical bath deposition (CDB) on an indium tin oxide (ITO) substrate, over which highly textured Bi2WO6 nanopillars were grown via a diffusion-and-aggregation phenomenon by electrostatic spraying deposition (ESD). The resulting heterojunction bilayer exhibited a photocurrent density value of 1.03 mA cm(-2) under visible light of 100 mW cm(-2) intensity. Widening the light absorptivity spectrum and reducing the charge recombination enhanced the performance of the heterojunction bilayer films for solar water splitting.
