Inverted Perovskite Photovoltaics using Flame Spray Pyrolysis Solution based CuAlO2/Cu-O Hole Selective Contact

We present the functionalization process of a conductive and transparent copper aluminum oxide, copper oxide alloy. The copper aluminum oxide, copper oxide powders were developed by flame spray pyrolysis and their stabilized dispersions were treated by sonication and centrifugation methods. We show that when the supernatant part of the treated copper aluminum oxide, copper oxide dispersions is used for the development of hole transporting layers the corresponding inverted perovskite solar cells show improved functionality and power conversion efficiency with negligible hysteresis effect.

Comment on: A significant enhancement in visible-light photodetection properties of chemical spray pyrolysis fabricated CdS thin films by novel Eu doping concentrations [Sens. Actuator. A Phys. 301 (2020) 111749]

In a recent paper [Sens. Actuator. A Phys. 301 (2020) 111749] Shkir et al. have studied the structural, optical and photo-electrical properties of the CdS thin films as a function of Eu doping concentration. The authors have used a wrong equation to calculate the refractive index and obtained values are incorrect. Consequently, the optical properties obtained based on the refractive index such as real and imaginary parts of dielectric constant, dielectric loss, optical conductivity, nonlinear refractive index (n2), linear and third-order non-linear optical susceptibility are wrong.

Uniformly Distributed Fe$_2$O$_3$ Nanoparticles Thin Films Synthesized by Spray Pyrolysis

Thin films of uniformly distributed Fe2O3 nanoparticles have been prepared on single crystal silicon and glass substrates by a spray pyrolysis technique in a single step using a mixture of water and ferrocene dissolved in xylene. The size distribution of nanoparticles is found to be in the range of 20 nm to 30 nm. The films have been characterized by X-ray diffraction, scanning electron microscopy and Raman spectroscopy techniques. The uniformity of the grown film was evident from the electron microscopic images on both the substrates. The crystallinity and band gap were investigated using X-r…

Effect of annealing treatment on the structural, optical and magnetic properties of ZnSe thin films grown by spray pyrolysis

Many investigations and reviews show that II-VI compound semiconductor 1-D nanostructures have a great potential for the future electronic and optoelectronic applications. As an important II-VI semiconductor, ZnSe is one of the most significant materials with prominent applications in this issue. In the present work, we firstly provide a comprehensive investigation of the magnetic properties like magnetization and magnetic susceptibility of ZnSe nanostructures as a 1-D quantum many body. The magnetic study of this metal reveals a ferromagnetic-antifferomagnetic transition upon cooling. Magneti…
