Abstract
Solar cells are manufactured by a simplified method in which a single protective layer acts as an anti-reflection coating and an encapsulation. In cases where the junction is formed by ion implantation techniques, the same layer also serves as the implantation oxide. In addition, this multi-purpose layer may also serve as a mass analyzer, allowing the desired species of ions to reach the surface of the semiconductor but blocking the heavier undesired species. The necessary contacts may be formed prior to implantation, and the use of alloyed aluminum contacts with aluminum oxide passivation permits a simplified contacting procedure. A fully automatic contacting method and configuration for linear materials is also disclosed.
