A flexible hybrid heterojunction PbS colloidal quantum dot solar cell, where the photoactive layers are deposited using a solution processed fabrication approach under ambient condition and at room temperature is presented. The bending stability of the obtained solar cell is evaluated. The results show that the solar cell exhibits high bending stability and even under the bent state the cell al...

We report a hybrid energy cell that can simultaneously or individually harvest wind, solar, and chemical energies to power some electronic devices. By utilizing the wind driven relative rotations between a polytetrafluoroethylene film and an etched Al film attached on two acrylic tubes, the fabricated triboelectric nanogenerator (TENG) can deliver an open-circuit voltage of about 90 V, a short-...

In this paper, we present a simple, low-cost and flexible hybrid cell that converts individually or simultaneously low-frequency mechanical energy and photon energy into electricity using piezoelectric zinc oxide (ZnO) in conjunction with organic solar cell design. Since the hybrid cell is designed by coupled piezoelectric and photoconductive properties of ZnO, this is a naturally hybrid archit...

Conducting p-type polymer layers on n-type Si have been widely studied for the fabrication of cost-effective hybrid solar cells. In this work, time-of-flight secondary ion mass spectrometry (TOF-SIMS) is used to provide three-dimensional chemical imaging of the interface between poly(3,4-ethylene-dioxythiophene):polystyrenesulfonate (PEDOT:PSS) and SiOx/Si in a hybrid solar cell. To minimize st...

Increasing of net energy storage (Q net) and discharge time of phase change material (t PCM), simultaneously, are important purpose in the design of solar systems. In the present paper, Multi-Objective (MO) based on hybrid of Particle Swarm Optimization (PSO) and multiple crossover and mutation operator is used for Pareto based optimization of solar systems. The conflicting objectives are Q net...

Inorganic/organic hybrid radial heterojunction solar cells that combine vertically-aligned n-type silicon nanowires (SiNWs) with poly(3,4-ethylenedioxythiophene):poly(styrene-sulfonate) (PEDOT:PSS) have great potential for replacing commercial Si solar cells. The chief advantage of such solar cells is that they exhibit higher absorbance for a given thickness than commercial Si solar cells, due ...

Various antireflection thin films are often used to cover glass to increase solar cell electrical parameters. In the recent years many efforts have been done to develop and improve of solar cell films with high electrical output. One of the most important challenges of obtaining of high-efficiency thin films of solar cells is creation an effective light trapping system. The new polymeric protec...

Abstract. Organic and hybrid bulk-heterojunction solar cells are investigated. We describe the synthesis and solar cell characteristics of well-defined functional thiophene dendrimers. Three-dimensional morphologies of the polymer – metal oxide bulk heterojunctions are analysed with electron tomography and are analysed and simulated with stochastic models, to establish the effect of processing ...

tellurium (te) nanostructures have been successfully synthesized via a simple hydrothermal methodfrom the reaction of a tecl4 aqueous solution with thioglycolic acid (tga) as a reductant. tga can be easily oxidized to the corresponding disulfide [sch2co2h]2, which in turn can reduce tecl4 to te. the obtained te was characterized by xrd, sem, eds, and drs. the effect of reducing agent on morphol...
