Perovskite-based solar cells have attracted much recent research interest with efficiency approaching 20%. While various combinations of material parameters and processing conditions are attempted for improved performance, there is still a lack understanding in terms the basic device physics functional that control efficiency. Here we show perovskite-based two universal features: an ideality factor close to space-charge-limited current regime. Through detailed numerical modeling, identify...
Organic–inorganic hybrid perovskite solar cells based on CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3−x</sub>Cl<sub>x</sub>and undoped poly(3-hexyl thiophene) as the hole transporting layers fabricated under ambient air conditions by solution processing.
Abstract The field of printed organic electronics has not only made flexible devices accessible but also allows the production process toward a high throughput industrial scale. current research involves inkjet‐printing an indium tin oxide‐free large‐area hybrid electrode compose conductivity layer (PEDOT: PSS) as main and inorganic silver nanoparticles‐based grid/film for auxiliary electrode. bottleneck in roll‐to‐roll is time required conductive inks to dry sinter. Flash sintering used...
In recent years, the proliferation of smart gadgets has increased demand for information displays; fortunately, organic light-emitting diodes (OLEDs) show great promise use in display, lighting, and signage contexts. This research demonstrates inkjet printing dielectric materials to provide maskless emission area patterning electrical isolation large-area OLEDs on flexible/rigid indium tin oxide (ITO)-coated substrates, avoiding need typical photolithography steps, including etching lift-off...
Superhydrophobicity in nature is the result of multiscale (hierarchical) roughness which consists nano-asperities superimposed on micrometer scale roughness. A low-cost superhydrophobic surface was prepared by depositing soot Vaseline coated glass substrates. The rapidly without any sophisticated fabrication facilities. exhibited a remarkably high water contact angle 161 deg and roll-off 3 deg. Atomic force microscopy (AFM) done revealed very rough surface. features with enhance repellency....
Large area Organic Light Emitting Diodes (OLEDs) are promising candidates for next generation solid state lighting application, with very good efficiencies and performances. OLED unit consists of thin layers organic materials over a large the major challenge remains in fabrication devices without defects, which cause sudden failure. Phosphorescent were fabricated an emissive 8 cm2 x various factors contributing to formation defects non-uniformity identified mechanism short was studied....
To fabricate fully solution-processed small-molecule organic light-emitting diodes (OLEDs), we investigate the slot-die coating technique for electron transport layer (ETL). 2,2',2"-(1,3,5-Benzinetriyl)-tris(1-phenyl-1-H-benzimidazole) (TPBi) was dissolved in methanol and coated as ETL applied multilayer OLEDs with Bis(4-phenylthieno[3,2-c]pyridinato-N, C2') (acetylacetonate) iridium(III) (PO-01) doped 4,4'-Bis(carbazol-9-yl)biphenyl (CBP) host an emissive layer. The provides efficient...
