Organic Photovoltaic: Patent Survey
Seminar TU Eindhoven 22/05/ 2012
Seminar TU Eindhoven22/05/2012
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 Eindhoven22/05/2012
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

2001 seems to be the beginning of an exponential increase in the number of published patents for the
OPV field

Results: countries
Example: Results for the General
OPV
For all the researches, the top 5 countries are Japan, USA, China, Korea and World, the first European
country is Germany.

Results for OPV + Textile substrate
The research on textile as substrate started later than the others but is becoming more important
Seminar TU Eindhoven22/05/2012
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 Eindhoven22/05/2012
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
