An overview of layer-by-layer assembly technique for solar energy conversion is comprehensively elucidated and summarized. [Display omitted] •Design principle for Layer-by-Layer (LbL) assembly is elucidated.•Latest developments of LbL-assembled photocatalysts and photoelectrodes are recapitulated.•Structure-performance correlation of LbL-assembled nanoarchitectures is unleashed. Heterostructured photosystems constructed by exquisite interface engineering have sprung up in solar-powered photocatalysis and photoelectrocatalysis, and have been attracting enduring interest in the past few decades. Among the diverse synthesis strategies, layer-by-layer (LbL) assembly offers a promising and robust platform for design of multifarious spatially multilayered nanoarchitectures by virtue of simplicity, versatility, easy accessibility and universality. However, LbL self-assembly of multilayered photocatalysts and photoelectrodes are in the infant stage. In this review, fundamental understanding on LbL assembly including principle, molecular interaction, influencing factors, and operation methods are concisely introduced. Most importantly, we comprehensively summarized the latest developments on LbL assembly of spatially multilayered nanoarchitectures with multiple dimensionalities and elucidated their advantages in fabricating high-performance photocatalysts and photoelectrodes. Furthermore, applications of LbL-assembled nanoarchitectures in diverse fields including environmental remediation, hydrogen production, selective organic transformation, and photoelectrochemical water splitting are systematically introduced. It is expected that our review can provide enriched information on rational design and construction of LbL assembled nanostructures for solar energy conversion.
