Abstract:
Introducing an anatase TiO2 passivation layer enhances carrier transport and suppresses recombination in BiVO4. Coupling the optimized photoanode with a Ta3N5 back photoanode broadens light absorption, and subsequently integrating a Si solar cell enables unassisted PEC water splitting with a 3.1% STH efficiency.

Polymer Classification: Crystallinity
Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...
