Recent advances in large-area optoelectronics research have demonstrated the tremendous potential of copper(I) thiocyanate (CuSCN) as a universal hole-transport interlayer material for numerous applications, including, transparent thin-film transistors, high-efficiency organic and hybrid organicinorganic photovoltaic cells, and organic light-emitting diodes (OLEDs). CuSCN combines intrinsic hole-transport (p-type) characteristics with a large bandgap (>3.5 eV) which facilitates optical transparency across the visible to near infrared part of the electromagnetic spectrum. Furthermore, CuSCN is readily available from commercial sources while it is inexpensive and can be processed at low-temperatures using solution-based techniques. This unique combination of desirable characteristics makes CuSCN a promising material for application in emerging large-area optoelectronics. In this review article, we outline some important properties of CuSCN and examine its use in the fabrication of potentially low-cost optoelectronic devices. The merits of using CuSCN in numerous emerging applications as an alternative to conventional hole-transport materials are also discussed.

e UV-Vis absorption and conductivity properties of the organic sample cochineal (Dactylopius coccus Costa) were modified by using it as a reducing agent in the biosynthesis of silver nanoparticles. is was done in a straightforward way in order to allow its possible application in organic devices. e biosynthesized solution exhibited a hybrid material with a UV-Vis absorbance range from 205 to 650 nm. e sizes of silver nanoparticles of the hybrid material were between 5 and 10 nm. X-ray diffraction (XRD) revealed silver structures, when samples were dried at 100°C. At 40°C, the structures detected were chlorargyrite (AgCl) and silver oxide (Ag 2 O). e nucleation and subsequent growth of the hybrid thin film on the substrates indicated an increase of clusters and roughness in comparison to thin films made solely from cochineal. e thin films of hybrid materials showed an improvement of 40% in their electrical potential. e stability at room temperature demonstrated that the hybrid material could be useful as a potential candidate for photoactive thin films in organic devices.

“…ZnO nanorods [24] or PCBM [25], ETM [26] are able to minimize the band offset at the conduction band minimum (CBM) and allow building almost ideal contact at ETM/LHM interface. However HTM very often present large band offsets at valence band maximum (VBM) and low carrier mobility [23,[27][28][29]. Alternatively, PSC without HTM layer was proposed as a solution towards high efficiency.…”

Influence of Schottky contact on the C-V and J-V characteristics of HTM-free perovskite solar cells

et al. 2017

The influence of the Schottky contact is studied for hole transport material (HTM) free CH3NH3PbI3 perovskite solar cells (PSCs), by using drift-diffusion and small signal models. The basic current-voltage and capacitance-voltage characteristics are simulated in reasonable agreement with experimental data. The build in potential of the finite CH3NH3PbI3 layer is extracted from a Mott-Schottky capacitance analysis. Furthermore, hole collector conductors with work-functions of more than 5.5 eV are proposed as solutions for high efficiency HTM-free CH3NH3PbI3 PSCs.
