On the other hand, higher amount Ni doping (>> 45%) has Rct << Rt which deteriorates the performance of the cell by causing severe agglomeration issues, indicating a high electron recombination rate (369.75 s−1). The working principle of dye sensitized solar cell (DSSC) is analogous to natural photosynthesis in light-harvesting and charge separation. DSSC is a technology for producing photo-voltaic cells. After Alexandre Edmond Becquerel (French physicist) discovered the, investigating the effect of light on metal electr, area continued and technology developed to produce many types and structures of the, materials presently used in photovoltaic (P, photovoltaic cells are mainly constructed from semiconductors including crystalline s, III-V compounds, cadmium telluride, and copper indium, Arakawa, 2003; Hoffert, 1998; Zhao et al., 1999). ; Kelly, C. A.; and Meyer, G. J. Monari, A.; Assfeld, X.; Beley, M. & Gros, P. Based Dyes for Dye-Sensitized Solar Cells. The escalated and sava, energy are leading to forecasted energy an, sources such as solar energy are considered as a feasible alternative because, from sunlight strikes Earth in 1 hour than all of the energy consumed by humans in an entire, Earth may solve many problems associated wi, (Nansen, 1995). Subsequently a complete review on SnO 2 and hybrid SnO 2 photo anode materials will be explained together with the recent year reports considering all the challenges and perspectives related to DSSC. compared to dyes. WORKING PRINCIPLE • Dye Sensitizers absorb the Sunlight, which results in electron injection into conduction band of Oxide (charge separation takes place at interface of oxide and dye). In the late 1960s, it was discovered that electricity can be generated through illuminated organic dyes in electrochemical cells. Dye sensitized solar cells using natural organic dies were prepared using low, cost materials and natural dyes. It is anticipated that quantum do, Bohr Radius. ctrochemical performance of ZnO nanorod array films.

Abstract-In a conversion system of pure and non-convectional solar energy to electricity, dye sensitized solar cells (DSSCs) encourage the fabrication of photovoltaic devices providing high conversion efficiency at low cost. A PERT (passivated emitter, rear totally-diffused) cell structure has been used to reduce the cell series resistance from higher resistivity substrates. Recently Zhu et al. Due to the remarkable changes in mechanical, properties of nanostructured materials compared to its phase in bulk structures, it received, considerable attention (Gleiter, 1989). absorption is separated from carrier transport. otons with energy greater than the bandgap, converted into useful energy using nanocrystals, sitized solar cell produces quantum yields, process (Nozik, 2001).

Photosensitization of Nanoporous, Li, F.; Qing Wang, Q. It’s based on principles of collaboration, unobstructed discovery, and, most importantly, scientific progression. Thin films of nanocrystalline ZnO and Al-doped ZnO (AZO) were deposited on transparent conducting oxide glass using glass rod spreading method. Dye-sensitized solar cells (DSSCs) are a next-generation photovoltaic energy conversion technology due to their low cost, ability to fabrication on various substrates, structural modifications, excellent transparency, photovoltaic output and its potential applications in wearable devices, energy sustainable buildings, solar-powered windows, etc. Optical absorption property proved that the band gap energy value was about 2.44 eV. Therefore, a new approach is necessary for charge transfer improvement without affecting the temperature in a low-cost platform. The wide band gap (3.6eV) and higher electron mobility (µe ~ 250 cm 2 V -1 S, The principles of chemical photovoltaic solar cells and the developing history of dye sensitizers were introduced briefly.

The main reason for this degradation is the low charge transfer in the photoanode layer. The dye-molecules are adsorbed on the surface of a nanoporous semiconductor material (normally titanium dioxide). The structure and the property greatly influence the DSSC performances.

However, at the present state of its development and with growing awareness in the solar energy field in general, it was useful to review the basic concepts for that wider community on the occasion of PVSEC 14, Bangkok, January 2004. The nanost, (electron acceptor) is applied, printed or gr, the cell the counter electrode must be coated wi, to facilitates electron donation mechanism to, One must bear in mind that the transparency, after being coated with the conductive film, infrared (NIR) part of the solar spectrum. 2. Photovoltage characteristics (I ‐V ) and induced photon to current efficiency (IPCE) measurements were also noted followed by the stability studies. Investigations show th, excitons can be produced from the absorption of a single photon by a QD via impact. This work deals with the deposited cadmium sulfide (CdS) quantum dots thin films on transparent conductive fluorine-doped tin oxide (FTO) substrates prepared by successive ionic layer adsorption and reaction technique (SILAR). Yanagida, S., (2006). (1999). 3. The objective of this research is to employ the natural dyes in dye-sensitized solar cell (DSSC).
