SILAR deposited copper tin sulfide (Cu2SnS3) thin films were used to analyze the study of electrochemical impedance, capacitancevoltage characteristics and currentvoltage characteristics. The photoconversion efficiency of SILAR deposited CTS thin film-based photoelectrochemical cell elucidate with the help of capacitance-Voltage (C-V) Characteristics study by MottSchottky plot and corresponding...

Ferroelectric domain morphologies in s001d PbZr1−xTixO3 epitaxial thin films were studied using the phase-field approach. The film is assumed to have a stress-free top surface and is subject to a biaxial substrate constraint. Both the electrostatic open-circuit and short-circuit boundary conditions on the film surfaces were considered. The phase-field simulations indicated that in addition to t...

In this work, we present a novel organic complementary comparator constructed of Pentacene P-channel and Fullerene N-channel thin-film transistors. These organic semiconductor materials are chosen due to their popularity and high effect-field mobility. We fabricated two new organic fieldeffect transistor types, then we measured key parameters in order to create models being used in integrated c...

Polyelectrolyte multilayers built via the layer-by-layer (LbL) method has been one of the most promising systems in the field of materials science. Layered structures can be constructed by the adsorption of various polyelectrolyte species onto the surface of a solid or liquid material by means of electrostatic interaction. The thickness of the adsorbed layers can be tuned precisely in the nanom...

A continuous flow of hot electrons that are not at thermal equilibrium with the surrounding metal atoms is generated by the absorption of photons. Here we show that hot electron flow generated on a gold thin film by photon absorption (or internal photoemission) is amplified by localized surface plasmon resonance. This was achieved by direct measurement of photocurrent on a chemically modified g...

Excimer laser textured thin film silicon and poly 2-methoxy-52 -ethylhexyloxy -1,4-phenylenevinylene bilayer solar cells are fabricated and characterized with air mass 1.5 simulated solar irradiation. The polymer layer increases the light harvesting capability of the cell and increases the shunt resistance while increasing open circuit voltage. The highest efficiency of 0.87% for the thin film ...

A simple and fast method was developed to determine the quantum efficiency and short circuit current of thin-film silicon solar cells prepared on periodically or randomly textured surfaces. The optics was studied for microcrystalline thin-film silicon solar cells with integrated periodic and random surface textures. Rigorous Coupled Wave Analysis (RCWA) was used to investigate the behaviour of ...

A theoretical study of randomly rough interfaces to obtain light trapping in thin-film silicon solar cells is presented. Roughness is modeled as a surface with Gaussian disorder, described using the root mean square of height and the lateral correlation length as statistical parameters. The model is shown to describe commonly used rough substrates. Rigorous calculations, with short-circuit curr...
