Solar cells based on metal halide perovskite and polymer donor:nonfullerene acceptor blend absorbers have recently witnessed a significant rise in their photovoltaic performance. However, they still suffer from some instability issues originating from the ...

Herein we present the latest fabrication and characterization techniques for atomic layer deposition of Al2O3, ZnO, SnO2, Nb2O5, HfO2, Ga2O3 and TiO2 for research on dye-sensitized solar cell. In particular, we review the fabrication of state-of-the-art 3D host-passivation-guest photoanodes and ZnO nanowires as well as characterize the deposited thin films using spectroscopic ellipsometry, X-ray diffraction, Hall effect, J-V curves and electrochemical impedance spectroscopy.

The employment of 2D perovskites is a promising approach to tackling the stability and voltage issues inherent in perovskite solar cells. It remains unclear, however, whether other perovskites with different dimensionalities have the same effect on efficie ...

The present invention provides an improved redox couple for electrochemical and optoelectronic devices. The redox couple is based on a complex of a first row transition metal, said complex containing at least one mono-, bi-, or tridentate ligand comprising ...

The dye-sensitized solar cells based on the functionalized organic sensitizer, 3-(5-(5-(4-(bis(4-(hexyloxy)-phenyl)amino)phenyl)thiophen-2-yl)thiophen-2-yl)-2-cyanoacrylic acid (D21L6) exhibit comparable stability to the ruthenium sensitizers under 60 degr ...

The recently reported heteroleptic cyclometallated iridium(III) complex [Ir(2-phenylpyridine)(2)(2-carboxy-4-dimethylaminopyridine)] N984 and its isomer N984b have been studied more in detail. While photo- and electrochemical properties are very similar, D ...

Highly ordered 1D TiO2 nanotube arrays are fabricated and applied as nanocontainers and electron transporting material in CH3NH3PbI3 perovskite solar cells. The optimized device shows a power conversion efficiency of 14.8%, and improved stability under an ...

Perovskite solar cells have attracted increasing interest among the photovoltaic community in the last few years owing to their unique properties and high efficiency. In the present work, we report the fabrication of perovskite solar cells based on highly ...

Two D−π−A dyes based on the dithieno[3,2-b:2′,3′-d]pyrrole π-bridge (DTP) were synthesized, characterized using UV−vis absorption spectroscopy and electrochemistry, modeled using quantum chemical calculations, and used as sensitizers in dye-sensitized sola ...

A dyestuff shown by the formula (1), ML 1 L 2 L 3 (1) wherein M represents an element belonging to Group 8 to Group 10 of the long format Periodic Table, L 1 and L 2 individually represent a bidentate ligand shown by the formula (2), L 3 represents a biden ...

An efficient synthesis of N-(2 ',4 '-bis(hexyloxy)-[1,1 '-biphenyl]-4-yl)-N-(4-bromophenyl)-2 ',4 '-bis(hexyloxy)-[ 1,1 '-biphenyl]-4-amine (BPTPA donor, 5) was developed based on a new 4-step synthetic route. The BPTPA donor is used to quickly access two ...

Spiro-OMeTAD is a widely used hole transport material (HTM) in perovskite solar cells (PSCs), but its inherent low hole mobility and poor thermal stability affect the overall performance of PSCs. To overcome these limitations, we develop a series of fluore ...

Correction for 'Increasing efficiency of perovskite solar cells using low concentrating photovoltaic systems' by Hasan Baiget al.,Sustainable Energy Fuels, 2020,4, 528-537, DOI: ;10.1039/c9se00550a. ...

Rapid and facile synthesis of similar to 7 nm and similar to 100-400 nm nano-structures of anatase titania is achieved by exploiting the chemical nature of solvents through a microwave based approach. After using these nanostructures as a photoanode in dye ...
