Abstrakt: Analytical expressions have been derived for the effective radiator emissivity and view factor of a given optical cavity geometry as a function of radiator emissivity and reflectance of the shield and TPV device. Using these expressions, accurate predictions of the device optical response (J[sub SC] and Q[sub abs]) have been made for two different cavity configurations (Au shield and TPV device shield). Also, the measured and calculated results show that placing a TPV device into an array of TPV devices will lower its output performance by at least 1.7% (relative) compared to that measured using a Au shield.
