Abstract

Thermophotovoltaic (TPV) converters were developed and tested at the heat source operating temperature of 1,700 K. Rare-earth-doped yttrium aluminum garnet (YAG) and lutetium yttrium aluminum garnet (Lu, YAG) selective emitters, as well as a blackbody emitter, were coupled to InGaAs/InP photovoltaic (PV) cells and bandpass/infrared (IR) reflector filters. YAG-based selective emitters were adopted with Ho, Tm, and Er. PV cells had bandgaps of 0.51, 0.57, and 0.69 eV. Converter energy conversion efficiencies approaching 30%, as well as electrical output power densities near 2 W/cm{sup 2} were demonstrated. The overall performance of the filtered blackbody-based converter was found to be superior to the selective emitter YAG-based converters. The details of the measurements performed on the above converters and their individual components are presented.

Solar thermophotovoltaic electrical generator for remote power applications. Final report

Technical Report Fatemi, N S

This final report presents the results of an SBIR Phase I project. Several TPV converters were fabricated and tested. The converters consisted of rare earth doped yttrium aluminum garnet (YAG) and Lutetium yttrium aluminum garnet (Lu,YAG) selective emitters and a blackbody emitter, bandpass/infrared (IR) reflector filters, and InGaAs photovoltaic (PV) cells. The operating temperature of the heat source was 1700 K. The filtered blackbody based converter was found to be the most suitable candidate for Solar TPV applications as compared to selective emitter based converters. High output power density (about 2 W/cm2) and efficiency (26.9%) were observed for this converter.more »« less
Thermophotovoltaic energy converters based on thin film selective emitters and InGaAs photovoltaic cells

Journal Article Fatemi, N S ; Hoffman, R H ; Wilt, D M ; ... - AIP Conference Proceedings

This paper presents the results of an investigation to demonstrate thermophotovoltaic energy conversion using InGaAs photovoltaic cells, yttrium-aluminum-garnet- (YAG-) based selective emitters, and bandpass/reflector filters, with the heat source operating at 1100{degree}C. InGaAs cells were grown on InP by organometallic vapor phase epitaxy with bandgaps of 0.60 and 0.75 eV and coupled to Ho-, Er-, and Er-Tm-doped YAG selective emitters. Infrared reflector and/or shortpass filters were also used to increase the ratio of in-band to out-of-band radiation from the selective emitters. Efficiencies as high as 13.2{percent} were recorded for filtered converters. {copyright} {ital 1996 American Institute of Physics.}

A review of recent thermophotovoltaic energy conversion technology development at NASA Lewis Research Center

Journal Article Wilt, D M ; Chubb, D L - AIP Conference Proceedings

NASA Lewis Research Center (LeRC) has had an ongoing research program in TPV since the late 1980{close_quote}s. This effort has included both in-house research programs on critical components such as photovoltaic cells (PV) and emitter materials, as well as an active contracting effort directed toward system and component development. Of particular note is the in-house development of thin film selective emitters fabricated from rare-earth yttrium aluminum garnets (YAG). Also developed at LeRC is a Monolithic Interconnected Module (MIM) consisting of many small InGaAs cells series interconnected on a single InP substrate.

Influence of ytterbium concentration on the emissive properties of Yb:YAG and Yb:Y{sub 2}O{sub 3}

Journal Article Panitz, J ; Schubnell, M ; Durisch, W ; ... - AIP Conference Proceedings

The Paul Scherrer Institut has initiated a project to develop a thermophotovoltaic (TPV) converter for residential heating applications. By economic reasons we have decided to design a thermophotovoltaic generator based on Si-cells and, accordingly, to make use of the selective emission properties of ytterbium containing emitter materials. In this contribution, we focus on the emitter materials and present results of an experimental study on the influence of ytterbium concentration on the emissive properties of ytterbium doped yttrium aluminum garnet (YAG) and yttria. The emitter materials were prepared by decomposition of nitrates and by co-precipitation methods with subsequent calcination at elevatedmore »« less
Thermophotovoltaic Converter Design for Radioisotope Power Systems

Journal Article Crowley, Christopher J ; Elkouh, Nabil A ; Murray, Susan ; ... - AIP Conference Proceedings

The development of lightweight, efficient power for emerging NASA missions and recent advances in thermophotovoltaic (TPV) conversion technology have renewed interest in combining radioisotope heat sources with photovoltaic energy conversion. Thermophotovoltaic power conversion uses advanced materials able to utilize a broader, spectrally tuned range of wavelengths for more efficient power conversion than solar cells. Spectral control, including selective emitters, TPV module, and filters, are key to high-efficiency operation. This paper outlines the mechanical, thermal, and optical designs for the converter, including the heat source, the selective emitter, filters, photovoltaic (PV) cells, and optical cavity components. Focus is on the emittermore »« less
