“…[33][34][35][36][37] It is also widely used as electrochromic materials, interface materials and transparent electrodes of organic electronic devices such as organic solar cells and organic light-emitting diodes. [38][39][40][41][42][43][44] Recent studies have shown that PEDOT: PSS also exhibits good performances in the aspect of photothermal conversion field. For instance, Liu et al disclosed that by coupling PEDOT: PSS with branching polyethylene glycol (PEG), the PEDOT: PSS-PEG nanoparticles show high stability in physiological environment, and nontoxicity to mice within 40 days in vivo, and exhibit good photothermal conversion properties, which are important and helpful for cancer treatment.…”

Open-shell radical meterials have received worldwide attention due to its potential application in highly efficient photothermal conversion field. However, it is still a challenge to enhance the chemical and photothermal stability of the open-shell small molecules and polymers. Herein, a stable open-shell oligo(3,4-dioxythiophene) radical PTTO2 was readily synthesized via simple BBr3-demethylation of the copolymer PTTOMe2 precursor prepared using cheap raw materials. The open-shell character of PTTO2 was carefully studied and confirmed via the signal-silent 1H-NMR spectrum, highly enhanced electron spin resonance signal comparing with PTTOMe2, as well as the ultral-wide UV-vis-NIR absorption and FTIR spectra and other technologies. Surprisingly, the powder of PTTO2 exhibit extremely wide absorption range from 300 to 2500 nm. The powder of PTTO2 can reach 274 ℃ under the same irradiation of 1.2 W cm-2, which is much higher 108 ℃ of the PTTOMe2. To date, PTTO2 stands as one of the low cost pure organic photothermal materials with super-high photothermal conversion performances.

“…Over the past few years, a wide range of CIL materials, including solution-processed metal oxides, conjugated polyelectrolytes, nonconjugated polyelectrolytes, and small molecules have been proved to be useful as a CIL for efficient OSCs by facilitating the electron collection at the interfaces. [16][17][18][19][20][21][22][23][24][25] Amine-containing nonconjugated polyelectrolyte, such as polyethyleneimine (PEI) forms thin interfacial dipoles, resulting in remarkable work function (WF) reductions in the electrodes. Thus, PEI has been frequently incorporated in inverted type OSCs by introducing PEI onto the surface of indium tin oxide (ITO).…”

Nonionic fluorosurfactant as a cathode interfacial layer for organic solar cells

Nonionic fluorosurfactants (NFSs) were first used as the cathode interfacial layer (CIL) of organic solar cells (OSCs). Commercially available NFSs, FS-31, and Zonyl FS-300 possess both hydrophilic part of ethylene glycol chains and hydrophobic part of fluoroalkyl chains, which endows NFSs with amphiphilic nature and thus significantly improves processability regardless of underlying surface conditions. In addition, NFSs spontaneously forms an interfacial dipole layer at the cathode interface to reduce the energetic barrier between the photoactive layer and cathode. The strength of the dipole moment is affected by the ratio of carbon to fluorine in the molecular structure of NFSs. Benefiting from the improved anode contact properties, the OSCs with high performing fullerene-based photoactive materials and NFS CILs exhibited high-power conversion efficiency of 9.1%, which is higher than that of the devices without CIL (6.6%).
