Method of preparing electronically connected optoelectronic devices, and optoelectronic devices

A method of preparing a plurality of electrically connected organic optoelectronic devices on a substrate comprising the steps of:

• a) preparing a plurality of organic optoelectronic devices comprising;
• i) providing a substrate,
• ii) providing a patterned layer of a first conductive material over said substrate,
• iii) providing a layer of organic optoelectronic material over said layer of first conductive material and
• iv) providing a patterned layer of a second conductive material over said layer of organic optoelectronic material, said patterned layer of second conductive material covering regions of said layer of organic optoelectronic material, said patterned layer of second conductive material defining a plurality of optoelectronic devices,
• b) at least partially removing regions of said organic optoelectronic material that are not covered by said patterned layer of second conductive material, and,
• c) providing electrical connections to electrically connect at least two of said plurality of organic optoelectronic devices.
