Structure in ternary blend systems for organic photovoltaics

Simultaneous Improvement in Short Circuit Current, Open Circuit Voltage, and Fill Factor of Polymer Solar Cells through Ternary Strategy

“…It was recently shown that the ternary strategy is expected to play an important role in achieving high performance PSCs, which inherit the major benefit of incorporating multiple organic materials in tandem cells while retaining the simple cell fabrication technology. − Ameri et al reported that the J sc can be improved from 8.6 to 12 mA/cm 2 by doping a low bandgap material into the system of poly­(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C61-butyric acid methyl (PCBM), resulting in the PCE increasing from 3.1% to 4% . Thompson et al demonstrated that the V oc can be gradually increased by only changing the doping weight ratios of two donors or two acceptors in ternary PSCs. − Chen and co-workers realized the FF improvement from 40.6% to 54.3% by employing P3HT as an additive to adjust the morphology of the active layer .…”

Synthesis of magneto-optically active polyanilines

“…The spectrum form of the triple signal confirms generation of nitroxyl radicals of the PANI. 1 The spin concentration is somewhat low because treatment of the PANI after oxidation in air decreases spins at the main chains, while radicals were specifically produced at the N-position of the PANIs. The g-values of the C-PANI-oxyl (g = 2.00516) in bulk indicate that the ESR signal of the C-PANI-oxyl is not derived from the charged species on the main chain.…”

“…Synthesis and application of electrically conducting polymers is a basis for 'plastic' electronic devices such as photovoltaics [1], organic transistors [2,3], and batteries [4][5][6]. The conducting polymers consist of a π-conjugated sequence main chain.…”

Vacuum deposited ternary mixture organic solar cells

“…The ternary OSC makes use of a single photo-active layer: a bulk heterojunction (BHJ) comprised of three light-absorbing species to confer broader absorption than the standard binary BHJ. Researchers have examined ternary OSCs with multiple donors (more prevalent in literature) [18][19][20][21][22][23][24][25][26], as well as multiple acceptors [27][28][29]. Initial results have been positive, with most researchers demonstrating enhanced short circuit current densities (J sc ) due to broader spectral responses.…”
