FLAT-PLATE SOLAR THERMOELECTRIC CONVERSION PANELS.
Abstract
Procedures were developed for constructing a lightweight solar energy converter, using thermoelectric materials sandwiched between flat sheets of aluminum. Two panels, each one foot square, have been delivered to the Flight Accessories Laboratory, Aeronautical Systems Division. Each panel contains 153 n-type PbTe elements and 153 p-type ZnSb elements, arranged in eighteen alternating rows of seventeen elements each. According to measurements made on test panels constructed in a similar fashion, the delivered panels are capable of an output of at least 1.33 w/sq ft when subjected to an incident energy of 1400 w/sq m, which is equal to the solar energy intensity at the Earth's distance from the sun. At this output, the solar panel weight 96 pounds per electricla kilowatt. The observed output is lower than is calculated from the properties of the materials used; however, it is anticipated that improved performance can be obtained in future panels. (Author)
