The invention is a method of forming a cadmium sulfide based buffer on a copper chalcogenide based absorber in making a photovoltaic cell. The buffer is sputtered at relatively high pressures. The resulting cell has good efficiency and according to one embodiment is characterized by a narrow interface between the absorber and buffer layers. The buffer is further characterized according to a second embodiment by a relatively high oxygen content.

A connector system is configured for macro motion. Two mating terminals are configured so that during macro motion cycles, the resistance between two terminals does not substantially increase. One terminal can have multiple, somewhat spherical-shaped mating surfaces while a mating surface on the other terminal can be flat. The mating terminals can be configured to provide desirable resistance performance after more than 5000 cycles of macro motion.
