Abstract

A photovoltaic cell is fabricated onto a polyimide film using an unbalanced RF magnetron sputtering process. The sputtering process includes the addition of 0.05% to 0.5% oxygen to an inert gas stream. Portions of the photovoltaic cell are exposed to an elevated temperature CdCl2 treatment which is at or below the glass transition temperature of the polyimide film.
