Silicon Solar Cell Optimization.

Abstract

This research program has resulted in improvements in vertical junction solar cell techniques leading to higher efficiencies and improved handleability. Vertical junction solar cells have now been fabricated with AMO conversion efficiency greater than 15% (25 C). A variety of cells have been fabricated including different groove depths, substrate thicknesses and bulk resistivities. Cell performance has been measured both before and after irradiation. Theoretical analysis has been performed to generate computer models of I-V curves for various cell geometries. These models have been compared with actual cell performance to aid in the understanding of the mechanisms responsible for cell performance.
