FIELD: physics.
SUBSTANCE: frame device according to the invention includes a substrate having a peripheral edge; a frame, having a groove which passes along the length and breadth of the frame, engages with the peripheral edge of the substrate; and a sealing lying inside the groove of the frame, which passes from the substrate to the frame adjacent thereto, wherein the sealing includes foamed poly-α-olefin having setting time shorter than or equal to 1 minute. The group of inventions also includes a photovoltaic cell, a second version of the frame device, a method of making the frame device and the sealing.
EFFECT: making improved photovoltaic cells with a simple design and low cost.
