Due to energy crises in the future, much effort is being directed towards alternate sources. Solar energy is accepted as a novel substitute for conventional sources of energy. Out of the long list of various types of solar cells available on the market, solid state photoelectrochemical solar cells (SSPECs) and dye sensitized solar cells (DSSCs) are proposed as an alternative to costly crystalli...

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-sensi...

Dye-sensitized solar cells (DSSCs) are categorized as some of inexpensive thin-film solar cells. The basis and foundation of these cells is a semiconductor that consists of an electrolyte and a light-sensitive anode. Titanium dioxide (TiO2) is a semiconductor that plays the role of anode and is the main constituent of these cells. In this paper, we have addressed the functionality and performan...

We have developed highly efficient, ambient temperature, solid-state ionic conductors (SSICs) for dye-sensitized solar cells (DSSCs) by doping a molecular plastic crystal, succinonitrile (SN), with trialkyl-substituted imidazolium iodide salts. High performance SSICs with enhanced ionic conductivity (2-4 mScm⁻¹) were obtained. High performance solid-state DSSCs with power conversion efficiency ...

We report the synthesis and characterization of five new donor–π–spacer–acceptor dye molecules with a diphenylamine donor, fluorene–1,2,5-oxadiazole spacers and a range of acceptor/anchor groups (carboxylic acid 1, cyanoacrylic acid 2 and 3, alcohol 4 and cyano 5) to facilitate electron injection from the excited dye into the TiO2 photoanode in dye-sensitized solar cells (DSSCs). Detailed photo...

Ga-doped ZnO [GZO] thin films were employed for the transparent electrodes in dye-sensitized solar cells [DSSCs]. The electrical property of the deposited GZO films was as good as that of commercially used fluorine-doped tin oxide [FTO]. In order to protect the GZO and enhance the photovoltaic properties, a TiO2 blocking layer was deposited on the GZO surface. Then, TiO2 nanoparticles were coat...

Anodized TiO2 nanotubes have received much attention for their use in solar energy applications including water oxidation cells and hybrid solar cells [dye-sensitized solar cells (DSSCs) and bulk heterojuntion solar cells (BHJs)]. High surface area allows for increased dye-adsorption and photon absorption. Titania nanotubes grown by anodization of titanium in fluoride-containing electrolytes ar...

The production of electricity in a greener and more sustainable way by employing renewable sources is great challenge modern times. Photovoltaic systems represent an important possibility because sunlight the most abundant source. In this review article, recent studies (from 2018 to present) involving novel iron copper complexes employed as dyes Dye-Sensitized Solar Cells (DSSCs) are reported; ...
