We report a solid-state-dye-sensitized solar cell with an efficiency of 4% over the standard air mass 1.5 spectrum s100 mW/cm2d. This was made possible by using an amphiphilic dye with hydrophobic spacers. We dense layer on the TiO2 surface w as anchors and with its hydrophobic isolating chains as blocking layer between hole conductor and TiO2. In addition we studied the dependence of the thick...

Energi radiasi matahari merupakan energi yang sedang giat dikembangkan saat ini. Indonesia negara sangat berpotensi untuk mengembangkan sel surya dikarenakan letak posisi berada di wilayah garis khatulistiwa (tropis). Sel alat mampu merubah sinar menjadi listrik. Teknologi telah ini adalah Dye Sensitized Solar Cell. menggunakan bahan kaca Indium Tin Oxide, dye titanium dioxide, cairan elektroli...

In this work, a method to assemble nanoscale hybrid solar cells in the form of a brush of radially oriented CdS nanowire crystals around a single carbon fiber is demonstrated for the first time. A solar cell was assembled on a carbon fiber with a diameter of ~5-10 μm which served as a core electrode; inorganic CdS nanowire crystals and organic dye or polymer layers were successively deposited o...

Herein we report an experimental analysis of the performance of photonic crystal based dye solar cells (PC-DSCs) as the incident light angle moves away from the normal with respect to the cell surface. Nanoparticle multilayers operating at different wavelength ranges were coupled to the working electrode of a dye solar cell for this study. The interplay between optical and photovoltaic properti...

The paper presents complex investigation of optical characteristics and some structural parameters of ZnS and ZnSe films obtained by the close-spaced sublimation technique under different growth condition. Investigation of optical characteristics was carried out in the 350-900 nm wavelength range for ZnS and 300-600 nm for ZnSe. Spectral distributions of transmission Т( ) and reflection spectra...

An inorganic layer and dye molecules have synergistically suppressed the recombination in a quantum dot sensitized solar cell (QDSSC), by the design of a structure featured TiO2-CdS-ZnS-N3 (N3: RuL2(NCS)2 (L = 2,2'-bipyridyl-4,4'-dicarboxylic acid)) hybrid photoanode. When fabricated into solar cells, a cobalt complex-based electrolyte rather than an iodine-based one was employed to obtain an i...

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...

In this paper we sensitized three free-metal azo days Dye 1, Dye 2 and Dye 3 based on 1,8-naphthalimide with n-propyl as the electron donor group. We used sulfonic acid and hydroxyl substituents as the electron acceptor anchoring group in synthesized dyes. The proposed dyes were sensitized from acenaphthene as the starting material by standard reactions and characterized by different techniques...

Degradation of dye solar cell performance based on the early changes in electrolyte color is predicted, allowing to estimate lifetime cells even before their efficiency declines. Previous predictive models commonly rely regression analysis predicted parameter; thus, they are unable capture degradation a significant decrease performance. tests, when accelerated, may take thousands hours. As such...
