“…The new generation of the components is highly valued because they are based on organic materials that offer not only flexibility and lightweight but also large surface and potentially low-cost devices [ 1 ]. Conjugated polymers are considered as one of the most successful and promising materials to be used as active layers in organic optoelectronic devices, such as in organic light-emitting diodes (OLEDs) and organic solar cells (OSCs) [ 2 , 3 , 4 ].…”

A new copolymer has been studied, which is formed by Poly(2-methoxy-5-(2-ethyl-hexyloxy)-1,4-phenylene-vinylene) (MEH-PPV) and poly(3-hexylthiophene) (P3HT). The choice of these π-conjugated polymers was based on their semiconductor characters and their great applicability in electronic organic devices. The structure and vibrational and optoelectronic properties were simulated by calculations based on DFT, TD-DFT, and ZINDO. This material shows original and unique properties compared to the basic homopolymers. Thus, the obtained results reveal that this copolymer can be mixed with the (6,6)-phenyl C61 butyric acid methyl ester (PCBM) to give existence to a new composite that can be used as an active layer for an organic solar cell.

“…However, achieving robust flexible OLEDs is extremely challenging and extensive research has looked into their development. [18,21,22] One of the bottlenecks in realizing high flexibility is the electrodes involved since the conventionally used indium tin oxide (ITO) is brittle and quickly breaks under the bending strain. [23] The probably most common alternative is 15-30 nm thin metal layers.…”

As solid‐state light sources based on amorphous organic semiconductors, organic light‐emitting diodes (OLEDs) are widely used in modern smartphone displays and TVs. Due to the dramatic improvements in stability, efficiency, and brightness achieved over the last three decades, OLEDs have also become attractive light sources for compact and “imperceptible” biomedical devices that use light to probe, image, manipulate, or treat biological matter. The inherent mechanical flexibility of OLEDs and their compatibility with a wide range of substrates and geometries are of particular benefit in this context. Here, recent progress in the development and use of OLEDs for biomedical applications is reviewed. The specific requirements that this poses are described and compared to the current state of the art, in particular in terms of the brightness, patterning, stability, and encapsulation of OLEDs. Examples from several main areas are then discussed in some detail: on‐chip sensing and integration with microfluidics, wearable devices for optical monitoring, therapeutic devices, and the emerging use in neuroscience for targeted photostimulation via optogenetics. The review closes with a brief outlook on future avenues to scale the manufacturing of OLED‐based devices for biomedical use.

“…Three parameters reflect OLED's luminous performance: quantum efficiency, lighting quality and efficiency. Quantum performance can be split into internal quantum performance and external quantum performance [45]. The external quantum efficiency η ext corresponds to the proportion of photons (N P ) released by the OLED in a given direction to the amount of injected (N C ) electrons.…”

Many changes have arisen in the world of display technologies as time has passed. In the vast area of display technology, Organic light-emitting diode is a recent and exciting discovery. Organic light-emitting diodes (OLEDs) have received a lot of curiosity among the researcher in recent years as the next generation of lighting and displays due to their numerous advantages, such as superior efficiency, mechanical flexibility and stability, chemical versatility, ease of fabrication, and so on. It works on the theory of electroluminescence, which is a mechanism in which electrical energy converts to light energy. Organic LEDs have a thickness of 100 to 500 nanometers or 200 times that of human hair. In OLEDs, organic material can be used in two or three layers. The emissive layer plays a key role in OLEDs. Polymers are used in the emissive layer to enhance the efficiency of OLEDs at the same time self-luminescence materials are used in OLEDs. In displays, this self-illuminating property removes the need for backlighting. Compared to LEDs and LCDs, OLED displays are smaller, lighter, and more portable.
