A bulk process is described which is capable of producing large area sheets about 8 micrometers thick having the property of light/electric power conversion at extremely high production rates (many m<2>/s) at low cost ( DOLLAR 1/m<2>). The devices have an inherently high efficiency 60-80% when laminated in an assembly to utilize both resolved light vectors. A light/electric power converter is described comprising a sheet containing oriented dipolar conducting linear structures forming an antennae array capable of absorbing light photons and producing a unidirectional electric current. These linear structures constitute submicron antennae and femto diode circuit elements. The individual antenna-circuit elements are self-ordered into the linear structure using a bulk process. The process utilizes (1) electro-ordering a suspension of elongated submicron metal crystals; or (2) molecules capable of absorbing a light photon and converting its energy to electric energy; or (3) visco-elastically stretch-orienting a light-electric responsive preformed heteropolymer. These submicron linear structures comprise a plurality of quantum well-steps, each with an assymetric tunnel junction at one end, in ordered three dimensional arrays. The manufacture uses a simple low cost bulk process and does not employ the submicron facility needed for the earlier planular process. |
