“…LabVIEW was used to display the current and voltage during a voltage sweep from 0 to 5 V. The voltage spacing was set to 0.04 V. The electrical properties of the DSSC were determined via the potential difference between both electrodes in DSSC. The percentage efficiency ( ) of DSSC is the ratio of power output ( out ) versus power input ( in ), where in is the total radiant energy incident on the active area of the cell calculated by (1).…”

Sensitization of heavy metal free organic dyes onto TiO 2 thin films has gained much attention in dye sensitized solar cells (DSSCs). A series of new kojic acid based organic dyes KA -were synthesized via nucleophilic substitution of azobenzene bearing different vinyl chains A -with kojyl chloride . Azo dyes KA -were characterized for photophysical properties employing absorption spectrometry and photovoltaic characteristic in TiO 2 thin film. The presence of vinyl chain in A -improved the photovoltaic performance from 0.20 to 0.60%. The introduction of kojic acid obtained from sago waste further increases the efficiency to 0.82-1.54%. Based on photovoltaic performance, KA achieved the highest solar to electrical energy conversion efficiency ( = 1.54%) in the series.

“…Solar energy is considered one of the most positive ways to decrease the climate change resulting from the use of fossil resources for energy generation [1][2][3][4]. The low-cost as well as environmentally friendly properties of dye-sensitized solar cells (DSSC) make the DSSCs one of the most promising classes of photovoltaic cells for the conversion of photon energy to electricity [5].…”

Co-sensitization is shown to be an effective method to improve the efficiency of dye-sensitized solar cells wherein ruthenium (ii)-based complex sensitizers (N749, N719) is co-sensitized with the metal-free indoline dye (D149), where photovoltaic efficiency of 5.40% is achieved by co-sensitized N749+D149 and efficiency of 4.94% is achieved by co-sensitized N719+D149. The assembled dye-sensitized solar cells were studied by UVvis absorption measurements of dye solutions, the absorption spectra of the dye-sensitized TiO 2 film along with co-sensitized TiO 2 film and current-voltage characteristics. The co-sensitized based device exhibits better photovoltaic performance compared to the devices fabricated from individual sensitizers. Upon optimization, the device made of co-sensitized N749+D149 yielded Jsc = 13.6 mA/cm 2 , Voc = 690 mV, FF = 0.576 and η = 5.40% and the device made of co-sensitized N719+D149 yielded Jsc = 13.3 mA/cm 2 , Voc = 660 mV, FF = 0.563 and η = 4.94%. This demonstrated that the performance of co-sensitized devices is improved from that of the devices sensitized with either N749 (4.56%), N719 (4.24%) or D149 (4.06%) under the same fabrication conditions.

“…DSSC is an electro-chemical solar cell which consists of four basic elements namely; Transparent conducting oxide electrodes, Sensitizer, Semi conducting layer, Electrolyte. In earlier stages of DSSC, the semi conducting layers used are Zinc Oxide (ZnO) and Tin Oxide (SnO 2 ) whose efficiency is proved to be lesser than 6% [4][5][6][7]. The breakthrough had come in 1991 by using Titanium dioxide (TiO 2 ) as semi conducting layer which was found to be higher than 7% efficiency using a Ruthenium sensitizer as a base [8].…”

For past several decades research in the field of photovoltaic has progressed from first generation solar cell to third generation solar cell. The dominance of solid state device which converts photons to electrons is a new challenge in technologies. In this work, a high efficient Dye Sensitized Solar Cell (DSSC) is fabricated. DSSC is easy to fabricate solar cell among the conventional pn-junction photo voltaic solar cells and even it is eco-friendly. A typical DSSC suffers from semiconductor liquid junctions and therefore concerns of electrolyte volatility and breakdown persists. By optimizing the sintering time, temperature, proper choosing of different types of sensitizer/dyes and the electrolyte, improves the efficiency of DSSC. It focuses towards developing DSSC on a small scale with the glass plates as electrodes coated with Titanium Oxide (TiO 2 ) and graphite. The plates are conducting which are coated with Fluorine doped Tin Oxide (FTO). To enhance the absorption power of the glass plates Eosin blue is chosen as a dye. These electrodes are placed in an electrolyte made up of Lithium Iodide (LiI) and Iodine (I). The electrical conduction mechanism of the fabricated DSSC is studied at 50 lux and also tested with cascaded series cell connection.Keyword: Working electrode; Counter electrode; Titanium Oxide (TiO 2 ); Eosin blue dye; Electrolyte IntroductionIn the last two decades the need for solar energy has increased. The photovoltaic market is still dominated by traditional solid-state pn junction devices, usually made from crystalline or amorphous silicon. Although the cost per watt of silicon solar cells has dropped significantly over the past decade, these devices are still expensive to compete with conventional grid electricity. It is an urgent task to develop much cheaper photovoltaic devices with reasonable efficiency for widespread application of photovoltaic technology. In this context, a new type of photovoltaic devices called "dye sensitized solar cells"(DSSCs) based on nanocrystalline TiO 2 was developed by O'Regan and Grätzel in 1991. This type of solar cells is featured by their relatively high efficiency (exceeding 11% at full sunlight) and low fabrication cost (1/10 th to 1/5 th of silicon solar cells). Since the birth of DSSCs, great efforts have been devoted in making these devices more efficient and stable. Long-term stability tests show good prospect of DSSCs for domestic devices and decorative applications in this century. Out of all solar energy resources, DSSC had gathered a great attention in the present world for its eco-friendly benefits. Due to the concept of wide band gap semi-conductors, DSSC existence had taken place in 1960 [1][2][3]. DSSC is also called as GRATZEL, cell named after its co-inventor. The reason for choosing DSSC is because of its good price and performance ratio, low cost, ability to work at wider angles, low light, long life, mechanical robustness and ability to work at low internal temperatures.The basic idea of a solar cell is to convert light en...
