TL;DR: An improved OLED structure which reaches fluorescent tube efficiency and focuses on reducing energetic and ohmic losses that occur during electron–photon conversion, which could make white-light OLEDs, with their soft area light and high colour-rendering qualities, the light sources of choice for the future.

TL;DR: Most present-day semiconductor devices use inorganic crystalline materials, with single-crystalline silicon dominating other materials like GaAs by about a factor of 1000, but organic semiconductors have recently gained much attention and are already broadly applied as photoconductors for copiers and laser printers.

TL;DR: In this article, a solvent post-treatment method was used to optimize poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) films as stand-alone electrodes for organic solar cells.

TL;DR: This review summarizes the current knowledge and provides a detailed description of the relevant principles for exciton-quenching mechanisms, both for phosphorescent and fluorescent emitter molecules, and further review methods that may reduce the roll-off and thus enable OLEDs to be used in high-brightness applications.

TL;DR: In this paper, the authors investigated quenching processes which contribute to the rolloff in quantum efficiency of phosphorescent organic light-emitting diodes (OLEDs) at high brightness: triplettriplet annihilation, energy transfer to charged molecules (polarons), and dissociation of excitons into free charge carriers.
