The main aims of this work were to produce and examine the characteristics of nanostructured ZnO in dye-sensitized solar cells. Parameters which are a ected by the e ciency such as precursor materials, morphology were investigated. The Raman spectroscopy was used to investigate transformation from bulk material to solution. General morphologies and detailed structural characterizations were obt...

The effect of light flux, redox couple concentration, and the number of panels on the electrical and chemical efficiency of a bipolar semiconductor photoelectrode array has been examined using a model based on the power characteristic curves of a single photoelectrochemical cell and the current-voltage characteristics of any desired electrolytic process. Data from a single bipolar CdSe//CoS pho...

A p-type boron arsenide photoelectrode was prepared from a material consisting of a thin layer of boron arsenide on a boron substrate. The structure of the material was identified using X-ray diffraction and scanning electron microscopy, and the surface composition was determined by means of X-ray photoelectron spectroscopy. The electrode was found to be photoactive under both visible light and...

A metal-free photoanode nanojunction architecture, composed of B-doped carbon nitride nanolayer and bulk carbon nitride, was fabricated by a one-step approach. This type of nanojunction (s-BCN) overcomes a few intrinsic drawbacks of carbon nitride film (severe bulk charge recombination and slow charge transfer). The top layer of the nanojunction has a depth of ca. 100 nm and the bottom layer is...

Photo-self-charging cells (PSCs) are compact devices with dual functions of photoelectric conversion and energy storage. By introducing a scattering layer in polymer-based quasi-solid-state dye-sensitized solar cells, two-electrode PSCs with highly compact structure were obtained. The charge storage function stems from the formed ion channel network in the scattering layer/polymer electrolyte s...
