Claims15
An electrophotographic active ink composition comprising:
- a thermoplastic polymer comprising a copolymer of an olefin and acrylic acid and/or methacrylic acid;
- active photovoltaic material comprising electron donor material and electron acceptor material;
- a charge adjuvant, and
- a liquid carrier.
A method of assembling a photovoltaic cell, said method comprising
- electrophotographically printing an active photovoltaic layer over a transparent anode using an electrophotographic active ink composition comprising a thermoplastic polymer comprising a copolymer of an olefin and acrylic acid and/or methacrylic acid;
- active photovoltaic material comprising electron donor material and electron acceptor material;
- a charge adjuvant, and liquid carrier;
- and
- electrophotographically printing a cathode over the active photovoltaic layer using a thermoplastic polymer comprising a copolymer of an olefin and acrylic acid and/or methacrylic acid;
- an electrically conductive material comprising carbon or metal;
- a charge adjuvant, and a liquid carrier.
An electrophotographically printed photovoltaic cell comprising a transparent anode, an electrophotographically printed active photovoltaic layer overlying the transparent anode, and an electrophotographically printed cathode overlying the electrophotographically printed active photovoltaic layer, wherein the electrophotographically printed active photovoltaic layer comprises a thermoplastic resin comprising a copolymer of an olefin and acrylic acid and/or methacrylic acid, and a mixture of electron donor material and electron acceptor material.
