Method of Fabricating Organic Thin Film and Organic Thin Film thereof

Patent Status: 

Patent Filed

Indian Patent Applicaton No: 

1585/DEL/2011

Overview: 

Improved crystallinity and formation of columnar structure in copper phthalocyanine (CuPc) films at lower temperature annealing is achieved by annealing them in the presence of an electric field.

Key Features: 

  • The crystallinity may be increased and nano column formation on the CuPc film can be hastened by annealing (150o to 200°C) it in the presence of an electric field
  • Higher crystallinity achieved at lower temperature finds application in many electronic and optoelectronic device fabrication with CuPc films
  • Improved organic solar cells may be fabricated with the electric field annealed CuPc films

Applications: 

  • Columnar structures formed on CuPc films can help interdigital heterojunction fabrication that are desirable for many device fabrication, including organic solar cells
