Solar Shades
Tensile Solar by SMIT
Brooklyn design company SMIT (Sustainable Minded Interactive Technology) has created Tensile Solar, a cool and lightweight shade powered by the sun (through CIGS photovoltaic cells).
From Wikipedia:
Copper indium gallium (di)selenide (CIGS) (CAS NO. 12018-95-0) is a I-III-VI2 compound semiconductor material composed of copper, indium, gallium, and selenium. The material is a solid solution of copper indium selenide (often abbreviated “CIS”) and copper gallium selenide, with a chemical formula of CuInxGa(1-x)Se2, where the value of x can vary from 1 (pure copper indium selenide) to 0 (pure copper gallium selenide). It is a tetrahedrally bonded semiconductor, with the chalcopyrite crystal structure, and a bandgap varying continuously with xfrom about 1.0 eV (for copper indium selenide) to about 1.7 eV (for copper gallium selenide). It is used as light absorber material for thin-film solar cells.
Tensile Solar is come in various designs: saddle, tent, pole mount and the last is intended to a larger architectural structures, such as a party tent.
