Themed collection SDG7: Affordable and Clean Energy

Semiconductor heterojunctions are pivotal in determining the overall photocatalytic efficiency. This review explores recent advances in diverse heterojunction types, charge transfer mechanisms and materials.

The n-type properties of carbon nanotubes are stabilized in the ambient atmosphere by hydrated water on a cationic molecular adsorption layer supplemented with Li⁺, which slows the diffusion of thermally active oxygen molecules.

When combined with salts to form polymer electrolytes, self-healing UPy-functionalized polymers lose their mechanical stability due to interactions between the ions and the UPy functionalities.

We use insulating polystyrene colloid particles to selectively cover the electron transport layer of n-i-p perovskite solar cells and investigate the effects of the coverage and lateral blocking distance on device performance.

The PF₆⁻ groups interact with Ni atoms to tightly attach to the NiO_x layer, resulting in enhanced carrier extraction of NiO_x.

Large area inverted type organic solar cells based upon a dye modified tin oxide electron transport layer are reported.

Cobalt–benzimidazole substituted metal–organic phthalocyanine combined with reduced graphene oxide was synthesized and utilized as an electrocatalyst, which exhibited improved current density and lower overpotential for oxygen evolution reaction.

The close interfacial contact facilitates the light-induced electron separation and transfer from ZIS to CoP, which synergistically yields an efficient hydrogen production performance.
