Book Description
Solvothermal method has been used for the synthesis of nanoparticles of II-VI semiconductors. Steps involved in the synthesis and chemistry have been discussed.Thin films of the corresponding nanoparticles have been deposited by spray technique. The effect of electric-field and iodine incorporation on optical, structural and morphological properties of the films has been studied and process of nanostructures formation has been discussed. Thin films of TiO2 and ZnO have been used to fabricate the DSSCs. The cells with TiO2 have shown the maximum efficiency of ~ 7.4% . The effect of underlying layer and barrier layers to achieve ~7.4% efficiency has been studied. Dye cells with ZnO as photo-electrode shows the maximum efficiency of ~4.7% for nanorod morphology film. Solid state dye sensitized solar cells have been fabricated by replacing the liquid electrolyte and organic dye with nanocrystalline CdX and HgX thin film layers. When CdTe nanoparticles are used as sensitizer the cell yields an efficiency of ~1% and for CdSe the efficiency of 0.87% has been achieved. When CdTe and CdSe nanorods are used as sensitizer cell efficiencies of 1.8% and 1.3% have been obtained, respectively.

Book Description
This book guides beginners in the areas of thin film preparation, characterization, and device making, while providing insight into these areas for experts. As chemically deposited metal oxides are currently gaining attention in development of devices such as solar cells, supercapacitors, batteries, sensors, etc., the book illustrates how the chemical deposition route is emerging as a relatively inexpensive, simple, and convenient solution for large area deposition. The advancement in the nanostructured materials for the development of devices is fully discussed.

Book Description
The second book of the four-volume edition of "Solar cells" is devoted to dye-sensitized solar cells (DSSCs), which are considered to be extremely promising because they are made of low-cost materials with simple inexpensive manufacturing procedures and can be engineered into flexible sheets. DSSCs are emerged as a truly new class of energy conversion devices, which are representatives of the third generation solar technology. Mechanism of conversion of solar energy into electricity in these devices is quite peculiar. The achieved energy conversion efficiency in DSSCs is low, however, it has improved quickly in the last years. It is believed that DSSCs are still at the start of their development stage and will take a worthy place in the large-scale production for the future.
