Optimization of Dye-sensitized Solar Cells Prepared by Pechini Sol-Gel Method

Natural Dye-Sensitized Solar Cells (NDSSCs) From Opuntia Prickly Pear Dye Using ZnO Doped TiO2 Nanoparticles by Sol- Gel Method

Natural dye-sensitized solar cells (NDSSCs) have gained considerable attention in the field of solar energy due to their simple fabrication, good efficiency, and low production cost. Natural dyes are environmentally and economically superior to ruthenium-based dyes because they are nontoxic and cheap. However, the conversion efficiency of dye-sensitized solar cells based on natural dyes is low....

Host-Sensitized Luminescence of Dy3¿ in Nanocrystalline b-Ga2O3 Prepared by a Pechini-Type Sol-Gel Process

Nanocrystalline undoped b-Ga2O3 and Dy -doped b-Ga2O3 were prepared through a Pechini-type sol-gel process. All the samples began to crystallize at 600°C, and the crystallinity increased with the increase of annealing temperatures until 1000°C. Field emission-scanning electron microscopy study revealed that the b-Ga2O3 :Dy 31 sample is composed of aggregated particles with sizes ranging from 40...

Solar Energy Conversion at Dye Sensitized Nanostructured Electrodes Fabricated by Sol-Gel Processing: Final Report

Dye-Sensitized Solar Cells with Anatase TiO2 Nanorods Prepared by Hydrothermal Method

The hydrothermal method provides an effective reaction environment for the synthesis of nanocrystalline materials with high purity and well-controlled crystallinity. In this work, we started with various sizes of commercial TiO 2 powders and used the hydrothermal method to prepare TiO 2 thin films. We found that the synthesized TiO 2 nanorods were thin and long when smaller TiO 2 particleswere ...

Dye-sensitized solar cells

The dye-sensitized solar cells (DSC) provides a technically and economically credible alternative concept to present day p–n junction photovoltaic devices. In contrast to the conventional systems where the semiconductor assume both the task of light absorption and charge carrier transport the two functions are separated here. Light is absorbed by a sensitizer, which is anchored to the surface o...
