摘要

Thermophotovoltaic (TPV) devices convert infrared electromagnetic radiation into electricity. The authors' research involves the use of strained-layer superlattices to enable TPV devices to operate at longer wavelengths than the current state of the art designs. To determine the performance of these devices, a novel test apparatus was designed and constructed. Here, the authors present a custom-built, cryogenic vacuum chamber for the testing and characterization of TPV samples. As TPV cells become sensitive to longer wavelength photons (lower source temperatures) in the infrared, the need to control the sample's ambient temperature becomes critical for accurate testing; thus, the tester includes two copper heat shields cooled via conduction with two liquid nitrogen reservoirs. A calibrated blackbody source is used to illuminate a temperature controlled sample in high vacuum (~10~(-6) Torr). The chamber temperature is extensively monitored and is designed to generate current-voltage (I-V) curves for TPV samples at different temperatures and input radiation in order to determine cell conversion efficiency. The system is evaluated based on the performance of its component systems.
