This paper describes synthesis of In2S3 nanoparticles by sonochemistry method and their application to enhance solar cells performance which In2S3 nanoparticles work as co-sensitizer for the first time. In2S3 is a narrow band gap semiconductor (2 eV) with conduction band higher than TiO2. Therefore it can transfer electron to the conduction band of TiO2. The effect of different parameters such ...

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.

Dye sensitized solar cell (DSSC) being one of the main focus in area of photovoltaic after silicon solar cell, modeling and estimating their parameters becomes important for their analysis and enhancement in their performance. We have proposed an analytical approach having no approximation for extracting various parameters of DSSC using a well known Lambert W-function technique. The model used ...

High photovoltaic efficiency is one of the most important keys to the commercialization of dye sensitized solar cells (DSSCs) in the quickly growing renewable electricity generation market. The heart of the DSSC system is a wide bandgap semiconductor based photoelectrode film that helps to adsorb dye molecules and transport the injected electrons away into the electrical circuit. However, charg...

Three natural pigments including wild iris, black pomegranate bark and black grapes were used as sensitizer in dye sensitized solar cells (DSSCs) based on TiO2 nanoparticles. The results showed that the DSSC made of black pomegranate bark was more efficient than the other cells due to its strong bonding with TiO2 nanoparticles. Longer electron lifetime, lower electron recombination, and lower...

We have synthesized a highly efficient organic dye for a dye-sensitized solar cell; the overall solar-to-energy conversion efficiency was 9.1% at AM 1.5 illumination (100 mW cm(-2)): short-circuit current density (J(sc)) = 18.1 mA cm(-2), open circuit photovoltage (V(oc)) = 743 mV and fill factor (ff) = 0.675.

A cyclometalated Ru dye bearing two triphenylamine groups to augment light absorption exhibits a power conversion efficiency (PCE) in excess of 7% in the dye-sensitized solar cell despite having a large molecular footprint on TiO(2).

Organic solar cell dyes containing the most common anchoring group, cyanoacrylic acid, are shown to be photolabile and undergo photoisomerization. This may have significant consequences for dye-sensitized solar cells, as isomerisation competes with electron injection and leads to modifications of the dye and surface arrangement.
