A cost-effective commercial soluble oxide cluster for highly efficient and stable organic solar cells

Layered bismuth selenide utilized as hole transporting layer for highly stable organic photovoltaics

“…S4c was L-Bi 2 Se 3 that prepared by three times spin-coating process. The over stacking of L-Bi 2 Se 3 nanoplates became the barrier for charge carrier transporting [36,37]. Based on the three devices results, we could concluded that the coverage ratio of L-Bi 2 Se 3 over the active layer was important for device performance.…”

Rational design of multifunctional star-shaped molecules with a 1,3,5-triazine core and different arms for application in organic light-emitting diodes and organic solar cells

“…The predicted λ e values decrease according to the sequences 1e > 1c > 1b > 1d > 1a for 1a-1e and 2e >2b > 2c > 2d > 2a for 2a-2e. The λ h and λ e values for molecules with benzo[c] [1,2,5]thiadiazole π-bridges (1a-1e) are smaller than that of TBTT. This implies that the presence of thiophene, anisole, aniline, 2,3-dihydrothieno [3,4-b] [1,4]dioxine, and 2-cyanoacrylic acid end groups leads to faster hole-and electron-transfer rates than those of TBTT.…”

“…In this paper, a series of D-π-A star-shaped small molecules with a 1,3,5-triazine core, aromatic derivatives as end groups, and benzo[c] [1,2,5]thiadiazole or thiophene S,S′-dioxide π-bridges that are intended for application in OLEDs and OSCs were systematically investigated. Analyses of the FMOs and local density of states found that the vertical electronic transitions associated with absorption and emission can be characterized as intramolecular charge-transfer (ICT) processes.…”

“…These star-shaped molecules contain a 1,3,5-triazine (TZ) core and benzo[c] [1,2,5]thiadiazole or thiophene S,S′-dioxide π-bridges (Scheme 1). Furthermore, we explored the optical and electronic properties of the molecules in order to gain further insight into the relationships between topologic structure and optical as well as electronic properties.…”

“…Ever since Tang reported organic electronics such as organic solar cells (OSCs) and organic light-emitting diodes (OLEDs) in the 1980s [1,2], the development of organic electronic devices has received significant attention because of their potential applications in next-generation full-color flat-panel displays, solar cells, and electronic sensors [3][4][5][6][7]. Compared with their inorganic counterparts, organic electronics have a number of advantages, such as their low cost, environmentally friendliness, ease of fabrication, and the potential to create large-area flexible panels.…”
