We are glad to announce the Special Issue "Nanostructured Solar Cells", published in Nanomaterials. This issue consists of eight articles, two communications, and one review paper, covering major important aspects of nanostructured solar cells of varying types. From fundamental physicochemical investigations to technological advances, and from single junction solar cells (silicon solar cell, dy...
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 ...
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...
In this research, CdS and PbS quantum dots were applied as the light sensitizers in TiO2 based nanostructured solar cells. The PbS quantum dots could absorb a wide range of the sunlight spectrum on earth due to their low bandgap energy. As a result, the cell sensitization is more effective by application of both CdS and PbS quantum dots sensitizers. The TiO2 nanocrystals were synthesized throug...
The dye-sensitized solar cells (DSSC) have been regarded as one of the most promising new generation solar cells. Tremendous research efforts have been invested to improve the efficiency of solar energy conversion which is generally determined by the light harvesting efficiency, electron injection efficiency and undesirable electron lifetime. In this review, various characteristics of dye-...
Recent development of carbon nanotubes materials as counter electrode for dye-sensitized solar cells
Dye-sensitized solar cells present promising low-cost alternatives to the conventional Silicon (Si)-based solar cells. The counter electrode generally consists of Pt deposited onto FTO plate. Since Pt is rare and expensive metal, nanostructured carbonaceous materials have been widely investigated as a promising alternative to replace it. Carbon nanotubes have shown significant properties such...
A pyrene photoluminescent layer is coated on the front side of a dye-sensitized solar cell to enhance the power conversion efficiency. The power conversion efficiency of the dye-sensitized solar cell coated with a pyrene photoluminescent layer improves from 9.12 ± 0.06% to 10.30 ± 0.11% (an improvement of 12.94%).

A zinc phthalocyanine (ZnPc) derivative (Zn-tri-PcNc-8) containing tri-benzonaphtho-condensed porphyrazine with one carboxylic and six diphenylphenoxy peripheral substitutions was designed and synthesized as a sensitizer for dye-sensitized solar cells (DSSCs). For the purpose of extending the absorption spectra while minimizing the formation of ZnPc molecular aggregates, bulky 2,6-diphenylpheno...
In this paper we studied preparation of working films of dye-sensitized solar cells using screen printed method. The organic dye based on phenoltiazine with cyanoacrylic acid as the electron donor group utilized as photosensitizer. Fluorine-doped thin oxide FTO coated glass is transparent electrically conductive and ideal for use in dye-sensitized solar cells. FTO glass was coated by screen pri...
