Martian environmental effects on solar cells and solar cell cover glasses

Abstract

The results of a study concerned with the effects of the Martian environment on the performance of solar cells are given. The results indicate that the efficiency of a power system composed of solar cells will be greatly reduced when subjected to dust storms such as may occur on Mars. Two factors are responsible for this, (1) accumulation of dust on the protective covers, and (2) damage to covers by pitting, cracking, and chipping. It is recommended that this type of power system not be used on Mars landing vehicles. Experimental procedures are described and results are summarized and damage assessed
