Title:
CERAMIC FILM AND METHOD FOR MANUFACTURING SAME, EMITTER, AND THERMOPHOTOVOLTAIC GENERATOR
Document Type and Number:
WIPO Patent Application WO/2023/204309
Kind Code:
A1
Abstract:
Provided is a ceramic film for a thermophotovoltaic (TPV) generator, the ceramic film having sufficient strength and making it possible to obtain a desirable radiation spectrum. A ceramic film (20) according to one embodiment comprises a substrate with holes formed therein. The substrate includes: a high-density region (1) which has a density higher than the average density of the entire ceramics film; and a low-density region (2) which has a density lower than the average density of the entire ceramics film. The high-density region (1) and the low-density region (2) are stacked in layers. The ceramic film is composed of an oxide ceramic containing a rare-earth element.
