ABSTRACT:
A liquid crystal coverslide for both protecting and concealing solar cells and solar cell arrays is disclosed. A conventional construction of an emulsion of encapsulated liquid crystal droplets is sandwiched between two pieces of polyester or silica to form a coverslide which is in turn mounted over a solar cell or solar cell arrays. The liquid crystal coverslide is electrically switched between transparent and opaque operating modes in order to achieve full light transmission-full power output or protection-concealment.
