AbstractDye sensitized solar cells are photoelectrochemical cells mimicking photosynthesis. They represent a new generation of solar cells which is intensively studied nowadays. This cell was fabricated using TiO2 nanoparticles coated on FTO glass, organic dyes as photosensitizer, PEDOT:PSS as counter electrode and iodide-triiodide as electrolyte. The present work aims at the use of low cost new organic dyes viz. biebrich scarlet, alizarine cyanine green and evans blue for DSSC as an alternative to metallic dyes. In the present work, I-V characteristics, energy or power conversion efficiencies of the dyes have been studied in different solvents. The photoelectrochemical properties of the dyes were observed under 1.5 AM condition.

ZnO is gaining importance in the electronics industry because of its availability of large sized single crystals, strong luminescence demonstrated in optically pumped lasers and the possibility of gaining control over its electrical conductivity. Dye Sensitized Solar Cells (DSSCs) is a photoelectrochemical system that incorporates a porous structured wide-bandgap oxide semiconductor (TiO2 or ZnO) film as the photosensitized anode that offers increased surface area for dye molecule adsorption. ZnO Nanoforest is comprised of high density, branched ZnO nanowire photoanodes. The overall light-conversion efficiency of the branched ZnO nanowire DSSCs is almost 5 times higher than the efficiency of DSSCs constructed by upstanding ZnO nanowires. The efficiency increase is due to increased surface area for higher dye loading and light harvesting, and also due to reduced charge recombination phenomena by providing direct conduction pathways along the crystalline ZnO nanoforest.

Dye-Sensitized Solar Cells (DSSCs) are among the most promising solar energy conversion devices of new generation, since coupling ease of fabrication and low cost offer the possibility of building integration in photovoltaic windows and facades. Although in their earliest configuration these systems are close to commercialization, fundamental studies are still required for developing new molecules and materials with more desirable properties as well as improving our understanding of the fundamental processes at the basis of the functioning of photoactive heterogeneous interfaces. In this contribution, some recent advances, made in the effort of improving DSSC devices by finding alternative materials and configurations, are reviewed.
