Abstract :
Thermophotovoltaic (TPV) is the technology for converting radiation from a heat source into electricity. Low bandgap TPV cells, such as GaSb, used in conjunction with spectral-modifying filters off a means for developing high efficiency (>20%) TPV systems. In this work, we report on a novel idea to further enhance TPV system efficiencies by integrating the GaSb PV cell front metal contact with the transparent metal mesh. A GaSb TPV Cell with transparent contact was fabricated and its electrical and optical characteristics measured.
