The hole transporting materials in perovskite solar cells have received significant attention recent years as a promising capable of developing high performance photovoltaic devices at low cost.
While the unabated race persists in achieving record efficiencies solar cells and other photonic/optoelectronic devices using lead halide perovskite absorbers, a comprehensive picture of correlated third-order nonlinear optical (NLO) properties is yet to be established. The present study aimed at deciphering role dopants multiphoton absorption intentionally engineered CsPbBr3 colloidal nanocrystals (NCs). charge separation plasmon-semiconductor conduction band owing hot electron transfer...
Developing metal–halide perovskite nanocrystals (NCs) has attracted great interest due to its potential application in optoelectronic devices. Herein, for the first time we report facile synthesis of Fe3+-doped cesium lead chloride (CsPbCl3) NCs along with their exciton relaxation dynamics. Efficient energy transfer occurs from host Fe3+ dopant, leading pink-colored dual emission consisting blue CsPbCl3 exitonic peak (410 nm) and red Fe-dopant state (584 nm). Interestingly, Fe-doping is...
For the first time we report design and syntheses of phosphonite coordinated ruthenium(II) sensitizers bearing ĈN̂N ligand and/or terpyridine derivatives carboxylate anchor (GS11, GS12. GS13) its application for hydrogen production over Pt-TiO2 system. These heteroleptic complexes exhibit broad metal-to-ligand charge transfer transition band whole visible regime extending up to 900 nm. DFT calculations these show that HOMO is distributed Ru Cl atom whereas; LUMO localized on polypyridile...
Indacenodithiophene-core-based D–π–A-type organic sensitizers with two different donor antennas (triphenylamine and phenothiazine) were designed synthesized for use as light-harvesting materials in dye-sensitized solar cell (DSSC) applications.
We have systematically tuned the spectral response of black dye using co-sensitization technique. In this study we selected two co-sensitizers coded as AK-01 and U01. The individual overall conversion efficiencies (η) these U01 are 6.20% 6.01%, respectively. A better power efficiency 10.21% 10.56% DSSC was observed when co-sensitized with U01, respectively, compare to single (9.18%). Both effectively overcome light absorption redox electrolyte improved dip in incident-photon-to-current...
Dye-sensitized solar cells (DSSCs) have received much attention in recent years owing to their efficient conversion of sunlight electricity. DSSCs became successful alternatives silicon photovoltaic devices by virtue low fabrication costs and easy preparation methods. In the dye plays key role. This review summarizes applications osmium sensitizers DSSCs. We also briefly discussed synthesis effect various electrolyte systems on device efficiencies.
In the light of diverse applications third-order nonlinear optical (NLO) chromophores in interdisciplinary fields, there is high demand for quest cost-effective and facile processing smart materials.

Abstract We have designed and synthesized a family of three novel benzodithiazole‐based hole‐transporting materials (HTMs) named as BTT‐TPA, BTT‐OMe BTT‐Me . These new HTMs are characterized by using 1 H, 13 C NMR, FTIR, elemental analysis, UV‐Vis spectrophotometer, cyclic voltammetry.
