Top Companies
-   Three types of companies were identified:


    - Major players in the field of electronics
      (Samsung, Lg, Sony, etc.)
           They are presents in all the steps of the entire
           OPV value chain.


    - Major players in the field of chemistry (BASF, Dupont
      de Nemours, Merck, etc.)


    - Few companies are presents in one field like Kodak
      well-known for their knowledge in printing

Other Results

 Statistics have been obtained about:
      Concepts (defined by Questel from the International
       classification)
      Assignees vs concepts
      Concepts vs years


     => Major trends are the same as described
 previously, the big companies involved in the OPV field work
 on all the value chain parts, from the materials to the final
 device.

Summary

From statistic
 The OPV research starts to grow exponentially in 2001
 Three types of companies were identified:
    -   Major players in the field of electronic (Samsung, Lg, Sony, etc)
    -   Major players in the field of chemistry (BASF, Dupont de Nemours,
        Merck, etc)
    -   Companies who are present in one field like Kodak


 Next Steps

OPV Patents - Organext

  • 1. Organic Photovoltaic: Patent Survey Seminar TU Eindhoven 22/05/ 2012
  • 2. Objectives  Identification of all the patents related to the OPV developments  Statistics :  Years  Countries  Assignees  Classifications (examples: C = chemistry; Metallurgy C07= Organic chemistry C07F= Acyclic, carboxylic or heterocyclic compounds containing elements other than C, H, N, S, Se or Te)  Creation of an easy-to-use database available for all the Organext partners Seminar TU Eindhoven 22/05/2012
  • 3. Tools 3 databases:  Questel : strategy of research, statistics  Espacenet : classification identification  Derwent : simplified presentation of patents (classifications, summary, adapted keywords, etc.) Topics :  OPV - General  Substrates : paper, zinc, textile, steel, glass  Encapsulation  Solution processed layers (classification B05- Applying liquids or other fluent materials to surfaces, in general )  + stability and lifetime Seminar TU Eindhoven 22/05/2012
  • 4. Research strategies Topics Keywords Classifications Results OPV General Organic solar cell(s), H01L-051/00, H01L-031, CO9K 13874 Photovoltaic cell(s), organic, Polymers, dyes, Gratzel Glass/ substrate Glass- windows- C08J-005/12+ - C03C 3525 Paper/ substrate Paper-cellulose- Cardbo D21H-027+, D21H-011+, B65C-005, B41, 656 B32B-029+, B31C Zinc/ substrate Zinc, ZnO, Zn C22C-009/04+, C22C-018+,C01G- 2820 009+,C23C-002/06+, C25D-003/22+, C25D-005+, C08K-005+, C23C-014 Steel/ substrate Steel, enameled steel C23D 84 Textile/ substrate Fabric, textile, cloth, weaver, B41F+, D01+, D02+, D03+, D04+, D05+, 923 Fiber, tissue, tricot D06 Encapsulation Encapsulant, encapsulated, B01J-013/20, B01J-013/22 2474 sealing, sealant, encapsulation, barrier(s) Solution B05 448 processed layers Seminar TU Eindhoven 22/05/2012

  • 11. Results: Top Companies vs Years Results for OPV + Paper substrate Seminar TU Eindhoven 22/05/2012
  • 12. Results: Top Companies vs Years Results for OPV + Textile substrate The research on textile as substrate started later than the others but is becoming more important Seminar TU Eindhoven 22/05/2012
  • 13. Results: Top Companies - Three types of companies were identified: - Major players in the field of electronics (Samsung, Lg, Sony, etc.)  They are presents in all the steps of the entire OPV value chain. - Major players in the field of chemistry (BASF, Dupont de Nemours, Merck, etc.) - Few companies are presents in one field like Kodak well-known for their knowledge in printing Seminar TU Eindhoven 22/05/2012
  • 14. Other Results Statistics have been obtained about:  Concepts (defined by Questel from the International classification)  Assignees vs concepts  Concepts vs years => Major trends are the same as described previously, the big companies involved in the OPV field work on all the value chain parts, from the materials to the final device. Seminar TU Eindhoven 22/05/2012
