Abstract

Thermophotovoltaic (TPV) systems are important for the clean energy transition due to their applications in waste heat recovery, solar energy harvesting, and thermal energy grid storage. This study presents a comprehensive investigation of the performance of TPV systems equipped with one‐dimensional photonic crystal filters. The optical characteristics of the filter comprised of porous SiO 2 nanoparticle and dense ZrO 2 films are numerically evaluated. The results demonstrate the choice of filter significantly influences the emitter temperature, power density, system efficiency, and spectral performance. Further, the analysis underscores the inherent tradeoff in designing optical filters between achieving elevated in‐band transmittance and maximizing out‐of‐band reflectance. Under a constant flux of 60 W cm −2 from a heat source a conventional double‐stack quarter‐wave optical filter achieves a TPV system efficiency of 28.9%. In contrast, an optimized filter structure, consisting of a double‐stack modified quarter‐wave optical filter, increases TPV system efficiency to 29.1%. Introducing the optimized filter with a graded index profile into the TPV system as a photon recycling tool results in a 27% TPV system efficiency. This is a significant improvement compared to the case without a filter, which has a system efficiency of 15.8%.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • A ZrO2/SiO2-based filter with a modified double-quarter-wave stack configuration leads to an efficiency of approximately 29%, compared to 16% without.

    “The modified double-quarter-wave stack configuration shows promising results, leading to an efficiency of approximately 29% compared to the case without, where the efficiency was only 16%.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
