Integrated silicon-based spectral reshaping intermediate structures for high performance solar thermophotovoltaics

Guozhi Hou et al.

Summary: Solar thermophotovoltaics (STPV) system utilizes an absorber and emitter to reshape wide-band solar radiation into narrowband infrared emission, converting it into electric energy with high efficiency. The study presents a silicon-based intermediate structure for spectral reshaping. The hierarchical Si NW structure acts as an absorber, exhibiting excellent absorption performance and low heat loss. The planar Si-W-SiN/SiNO structure functions as an emitter, showcasing selective narrowband absorption (emission) peak at the target wavelength. With a specific design, the overall efficiency of the STPV system based on this silicon-based intermediate structure can potentially exceed 29%.

Optical properties of hollow plasmonic nanopillars for efficient solar photothermal conversion

Haotuo Liu et al.

Summary: In this study, the optical properties and photothermal conversion performance of hollow and solid nanopillar structures based on different plasmonic materials (Ag, Au, Cu, TiN) were compared. The results show that hollow Au nanopillars exhibit the highest increase in photothermal conversion efficiency, by 34.14%. This enhancement is attributed to the promotion of local and propagating surface plasmon resonances in the hollow structure. Conversely, the increase in photothermal conversion efficiency for hollow TiN nanopillars is only 1.41%, as the solid TiN nanopillars already have high efficiency (97.19%). The hollow structure can enhance the photothermal properties of Plasmonic nanofluids, especially for precious metal materials with narrow-band absorption, such as Au and Ag.

Pattern-free solar absorber driven by superposed Fabry-Perot resonances

Haotuo Liu et al.

Summary: In this study, a pattern-free absorber was proposed, consisting of a TiN-SiO2-based multilayer structure, for solar energy utilization. Numerical results showed that the maximum average spectral absorption of a 3-cell multilayer structure reached 93.5% at wavelengths of 0.3-2.5 μm. The underlying physical mechanism was explained by the coupling of superposed Fabry-Perot resonances and the intrinsic absorption of TiN. The findings in this work deepen the understanding of FP resonance and pave a novel path for efficient solar thermal energy utilization.
