Uniform nanolayer coatings on photoelectrodes for water splitting are effective in improving their durability by isolating the semiconductor from direct contact with liquid electrolytes. Achieving a thin and uniform coating across the entire surface of nanostructured uneven photoelectrodes using wet processes remains a challenge. This study provides a strategy for the spontaneous formation of a uniform nanolayer of NiFeOx electrocatalyst on Ta3N5 nanorods (NRs) photoelectrodes mediated by acetonitrile (CH3CN) solvent and bulky metal ethylhexanoate complexes. Following the NiFeOx deposition through a spin-coating method on Ta3N5 NRs, the sample is immersed in CH3CN solvent for 12 h. This treatment effectively results in complete coverage of the complex structured surface of Ta3N5 NRs by the NiFeOx nanolayer. The nanocoating ensures the protection of Ta3N5 NRs and contributes to enhanced durability. This distinctive surface modification is applied to semitransparent Ta3N5 NRs photoanodes which is applicable to photovoltaic-photoelectrochemical tandem cells. This simple immersion method of bulky metal complexes into a thin and uniform layer on rough surfaces would have potential for various applications including (photo)electrochemical reactions and corrosion inhibitions.

The lack of attractive n-type thermoelectric materials greatly restricts their applications because most high-performance materials are p-type conductors, such as the kesterite compound Cu2ZnSnS4. This study reports high-quality n-type kesterite (Cu1−xAgx)2ZnSnS4 (CAZTS) single crystals that exhibit a record high dimensionless figure of merit value of 1.1 at approximately 800 K, primarily owing to Ag alloying, cation compositional optimization, and intrinsic low thermal conductivity. An n-type CAZTS-based single-leg device was fabricated using a Mo-barrier layer. The device exhibited a thermoelectric conversion efficiency of 3.4% at a temperature gradient of 473 K. This study provides insights into developing thermoelectric modules using environmentally friendly kesterite materials.

The development of an efficient conversion system to transform solar energy into chemical energy, such as renewable hydrogen, is a promising way to overcome energy problems. Photoelectrochemical (PEC) water splitting is a promising means of obtaining renewable hydrogen directly from water utilizing sunlight. Recent reports have demonstrated that a PEC cell with a tandem configuration (tandem cell) has the potential to realize a high solar-to-hydrogen (STH) energy conversion efficiency by solar water splitting. However, there are still many obstacles to the development of practical and cost-effective tandem cells. In particular, development of efficient photoanodes for the oxygen evolution reaction (OER) is a prerequisite for improving the STH efficiency. Herein, recent progress in developing (semi)transparent photoanodes for the OER, such as Fe2O3, BiVO4, and Ta3N5, is described based on the topics of preparation methods, semiconductor properties, and PEC performance. In addition, the strategies for enhancing the STH efficiency of tandem cells consisting of (semi)transparent photoanodes conjugated with photovoltaic (PV)-based cathodes are summarized. This Review is expected to provide guidelines for the future development of tandem cells capable of highly efficient and stable water splitting.
