Thermophotovoltaic Array Optimization

Abstract

A systematic approach to thermophotovoltaic (TPV) array design and fabrication was used to optimize the performance of a 192-cell TPV array. The systematic approach began with cell selection criteria that ranked cells and then matched cell characteristics to maximize power output. Following cell selection, optimization continued with an array packaging design and fabrication techniques that introduced negligible electrical interconnect resistance and minimal parasitic losses while maintaining original cell electrical performance. This paper describes the cell selection and packaging aspects of array optimization as applied to fabrication of a 192-cell array.

Development of Front Surface, Spectral Control Filters with Greater Temperature Stability for Thermophotovoltaic Energy Conversion

“…Conversion efficiencies for single module TPV cells with front surface filters have been previously reported to exceed 20% 2 . Conversion efficiencies for TPV arrays with front surface filters has been reported to exceed 12% 7 , with a power density in the range of 0.4 watts/cm 2 . These tests were performed using front surface spectral control filters that contained antimony selenide (Sb 2 Se 3 ) as the high index material.…”
