Multiple element solar cell - has semiconductor elements enclosed between conductive and insulating layers with ends folded over and interlocked

摘要

The solar cell for obtaining electrical energy from the sun's rays, has a series of semiconductor elements (25) each enclosed between two metal foil layers (11, 31) which are at least partly transparent to the sun's rays. Each foil layer is in contact with a respective layer (23, 24) of a give polarity forming the semiconductor element. A free end of each foil extends beyond a respective insulating layer (29, 43). The end of the shorter insulating layer is bent around the adjacent conductive layer (11) and the semiconductor layers. A series of elements can be interconnected by overlapping the free ends and interlocking them.
