چکیده
Here, we present the first application of molecular gel-mediated power-conversion enhancement of solar cells, which is based on the excimer emission from a transparent and colourless polymer film that encapsulates a pyrene nano-fibrillar assembly.

A New Microstructured DSC Photoelectrode for Potential High Power Conversion Efficiency
This paper includes an overview of general approaches and efforts to enhance the power conversion efficiency in dye-sensitized solar cells (DSC) and then the recent development of hierarchically structured photoelectrodes for DSC. Hierarchically structured photoelectrodes are made of submicron-sized aggregates of ZnO nanocrystallites. Such structured photoelectrodes retain the desired large sur...

This study investigated the influence of ZnO nanostructures on dye adsorption to increase the photovoltaic conversion efficiency of solar cells. ZnO nanostructures were grown in both tree-like and nanorod (NR) arrays on an AZO/FTO film structure by using a hydrothermal method. The results were observed in detail using X-ray diffraction, field-emission scanning electron microscopy (FE-SEM), UV-v...
متن کاملAcid azo dyes for efficient molecular photovoltaic: study of dye-sensitized solar cells performance
In this paper we sensitized three free-metal azo days Dye 1, Dye 2 and Dye 3 based on 1,8-naphthalimide with n-propyl as the electron donor group. We used sulfonic acid and hydroxyl substituents as the electron acceptor anchoring group in synthesized dyes. The proposed dyes were sensitized from acenaphthene as the starting material by standard reactions and characterized by different techniques...

In this study, aligned zinc oxide (ZnO) nanorods (NRs) with various lengths (1.5-5 µm) were deposited on ZnO:Al (AZO)-coated glass substrates by using a solution phase deposition method; these NRs were prepared for application as working electrodes to increase the photovoltaic conversion efficiency of solar cells. The results were observed in detail by using X-ray diffraction, field-emission sc...
متن کاملEnhanced efficiency of dye-sensitized solar cells doped with green phosphors LaPO4:Ce, Tb or (Mg, Zn)Al11O19:Eu
We have successfully introduced green phosphors LaPO4:Ce, Tb (G4) or (Mg, Zn)Al11O19:Eu (G2) into TiO2 photoelectrode of dye-sensitized solar cells. The conversion efficiency of the G4-doped device was enhanced by 30% compared with the pristine TiO2 photoelectrode. The green phosphor doped at 5-wt.% ratio contributed to the reduction of resistances of the surface and interface of the photoelect...
