GaSb-based thermophotovoltaic converters of IR selective emitter radiation

In this study, GaSb-based thermophotovoltaic converters for selective mantle-type Y$_{2}$O$_{3}$-based emitter covered with rare earth oxides Er$_{2}$O$_{3}$/Yb$_{2}$O$_{3}$ have been investigated. Matching the spectral response of the converters with the peaked emitter radiation wavelength $\lambda$ = 1540 nm provides a thermophotovoltaic conversion efficiency of more than 26% (0.4 W).
