Serge (fabric) Serge (fabric) Serge is a type of twill fabric that has diagonal lines or ridges on both sides, made with a two-up, two-down weave. The worsted variety is used in making military uniforms, suits, great coats and trench coats. Its counterpart, silk serge, is used for linings. French serge is a softer, finer variety. The word is also used for a high quality woolen woven fabric. The name is derived from Old French , itself from Latin , from Greek ("serikos"), meaning "silken". The early association of silk serge, Greece, and France is shown by the discovery in Charlemagne's tomb
Solar cell fabric Solar cell fabric Solar cell fabric is a fabric with embedded photovoltaic (PV) cells which generate electricity when exposed to light. Traditional silicon based solar cells are expensive to manufacture, rigid and fragile. Although less efficient, thin-film cells and organic polymer based cells can be produced quickly and cheaply. They are also flexible and can be stitched onto fabric. According to an article from New Scientist researchers have built a PV cell in the layers around a fiber, creating a tiny cylindrical cell. No longer limited to rooftops and poles, solar collection could work silently and unobtrusively from everyday objects.
