Vertical Junction Solar Cells.
Abstract
The goal of this program was to develop and evaluate an acceptable coversliding technology for vertical junction solar cells. The technical program was divided into the following sub-tasks: 1.0. to fabricate 80 vertical junction cells of msot recent configuration for evaluation as individual samples and for test module assembly. 2.1. to develop a satisfactory method for coversliding V.J. cells to withstand deep thermal cycle in space. 2.2. to establish welding parameters for V.J. cells and evaluate their weldability. 3.0. Using techniques from 2.1 and 2.2 four modules (4 cell each) to be fabricated and thermal cycled in dry nitrogen (115 c to +125 c 25 cycles) and thermal vacuum tested at 135 c. 4.0. based on results of tasks 2 and 3, two six cell modules to be designed: 1 soldered, 1 welded, and design to be discussed with COTR prior to finalization and 5.0. final design to be fabricated subjected to a thermal vacuum test at +135 c, thermal cycled -115 c to + 125 c, and characterized by I-V measurements and delivered to NRL for testing and evaluation.
