Solution-Processed MoS_x as an Efficient Anode Buffer Layer in Organic Solar Cells

Abstract

We reported a facile solution-processed method to fabricate a MoSx anode buffer layer through thermal decomposition of (NH4)2MoS4. Organic solar cells (OSCs) based on in situ growth MoSx as the anode buffer layer showed impressive improvements, and the power conversion efficiency was higher than that of conventional PEDOT:PSS-based device. The MoSx films obtained at different temperatures and the corresponding device performance were systematically studied. The results indicated that both MoS3 and MoS2 were beneficial to the device performance. MoS3 could result in higher Voc, while MoS2 could lead to higher Jsc. Our results proved that, apart from MoO3, molybdenum sulfides and Mo(4+) were also promising candidates for the anode buffer materials in OSCs.

Surface Modification of Nickel Sulfide Nanoparticles: Towards Stable Ultra‐Dispersed Nanocatalysts for Residue Hydrocracking

“…For OA‐NSNPs, the XPS C 1s spectrum shows a weak characteristic peak at BE=288.9 eV, which indicates the presence of −COO − groups (Figure a). In the S 2p spectrum of DDT‐NSNPs, a peak for the 2 p 1/2 orbital of divalent sulfide ions (S 2− ) is observed, which suggests the presence of DDT on the surface of DDT‐NSNPs …”

Effect of Radio Frequency Power on the Physicochemical Properties of MoS2 Films Obtained by rf Magnetron Sputtering

“…The three spectra are fitted with one peak with 1.18 eV of SOS. The black dotted line shows the peak maximum centered at 162.4 eV of S 2p 3/2 , and it concurs with the binding energy of the S 2− species . This provides concrete proof that MoS 2 thin films were successfully deposited by rf sputtering.…”
