A Summary of the International Workshops on Space Solar Cell Calibration and Measurement Techniques

The first two of a planned series of international workshops concerning space solar cell calibration and measurement techniques have been held within the past year. The need for these workshops arose from the increasing complexity of space solar cells coupled with the growing international nature of the market for space cells and arrays. The workshops, jointly sponsored by NASDA, ESA and NASA, have the objective of obtaining international agreement on standardized values for the AM0 spectrum and constant, recommendations for laboratory measurement practices and the establishment of a set of protocols for making interlaboratory comparison measurements. The results of the first two workshops, held in Waikiki, Hawaii, USA in 1994 and Madrid, Spain in 1995, are presented.
