This paper presents a TPV converter module for use with radioisotope heat sources such as the Department of Energy{close_quote}s General Purpose Heat Source (GPHS). The converter module utilizes an IR bandpass filter which transmits a band of energy at the optimum frequency for GaSb photovoltaic conversion and rejects long wavelength out of band energy with a broadband reflectance of greater than 98{percent}. Recent progress in optimizing IR bandpass filters and photovoltaic cells for use in the TPV module is summarized. Measured data on the transmittance and reflectance of the filters, quantum efficiency of the PV cells both with and without the filters are presented. The results of using these measured results in an experimentally confirmed analytical model of the TPV converter module to calculate the performance of the optimized components are discussed. An economical pilot process for filter production is also described. {copyright} {ital 1996 American Institute of Physics.}
