Organic photonics: Achievements and setbacks

摘要

Organic photonics is related to the production of optical devices of organic materials on a common technological platform. Scientific investigations performed in the area of organic photonics are aimed at the development of new-generation telecommunication and computer technologies and photovoltaic (PV) and organic light-emitting diodes (OLEDs). Though OLED technology has seen tremendous progress, it still can be improved further. Despite major progress towards achieving a high internal efficiency of energy conversion, there is still the potential to improve the external energy conversion efficiency for OLEDs. Layers of small organic molecules can be deposited by the well-known methods of vacuum or centrifugal deposition, which allow using long-developed equipment and thereby making production cheaper. Although the development of materials and structures continues, the majority of the basic problems have only been partly solved, and the problems in manufacturing efficient OLEDs deserve special attention.
