Description

CONTEXT

There are many organic compounds usable as electron donor known in the state of the art for the development of organic electronic devices such as photovoltaic devices.
However, most of these compounds do not give full satisfaction as their performances in terms of efficiency are less than that of the cells containing silicon. There thus exists a need for compounds having a cost price lower than silicon and being able to be used effectively as electron donor for said devices.

TECHNICAL DESCRIPTION

In the present work, the inventors have discovered that certain cobalt complexes present excellent properties of donor of electrons
Said compounds have the following formulas:


Example of compounds:

DEVELOPMENT STAGE

Organic solar cell comprising compounds as described above have been assessed on a laboratory scale.

BENEFITS

  • This process is simple, reproducible and inexpensive to implement (yield: 65 to 95%);
  • Compounds claimed are very good semiconductors

INDUSTRIAL APPLICATIONS

Present organic electron donor can be used in heterojunction-based organic solar cell in combination with an electrons acceptor.
