Abstract

The Solar Energy Research Institute (SERI) has been conducting field tests on amorphous silicon modules and analyzing the results in terms of both stability and performance. Both single p-i-n and tandem modules have been under evaluation for the past few years. This paper presents performance test results for several of these modules. Analytical models for efficiency and fill factor are presented. These models are used to project design lifetime performance. Mean square error curve fitting techniques are used to overcome data scatter. The models bracket best and worst case performance. A phenomena based, double exponential model is included to project end of life performance. This model primarily focuses on degradation due to light induced defects.
