Abstract
A new composition of matter is described comprising a stretch oriented electrically-conducting light-polarizing film. An improved light-electric power converting film uses molecular diodes (diads) in this film composition aligned head-to-tail by light and an electric field. The area of the film is utilized more efficiently by reversing the head-to-tail directions of the diads in adjacent areas. This film is laminated to an electrode structure connected to busbars on a substrate sheet. Current flow through the film is unidirectional between pairs of adjacent electrodes, and is summed on busbars connected to an external load. Two such films arranged orthogonally convert about 72% of the incident light power to electric power. A manufacturing device is disclosed. Critical Ranges of parameters are derived and experimental data presented.
