Patent ID: 8220930

Claim:
An integrated opto-electronic device used in a portable reflective projection system, comprising: a reflective polarizing composite film configured to receive a source light at a desired non-normal incident angle, polarize and reflect a first portion of said source light as polarized illumination light at a reciprocal angle to said desired non-normal incident angle; and a photovoltaic cell, adhered to an opposite side of said reflective polarizing composite film to said source light, configured to receive a second portion of said source light that passes through said reflective polarizing composite film and transform said second portion to photogenerated charge; both said reflective polarizing composite film and said photovoltaic cell are fabricated in an adherent stack on a semiconductor substrate, and said photovoltaic cell comprises: a plurality of reflective top electrical contact lines; a photon-to-electron converting photo diode; and a backside electrical contact; in a plannar configuration, wherein said plurality of reflective top electrical contact lines are regularly spaced in parallel in a plannar configuration with a constant desired spacing between each adjacent pair, placed in electrical contact to the top surface of said photo diode and covered by a plannar dielectric film, and said plurality of reflective top electrical contact lines are embedded into said reflective polarizing composite film.
