| 内容記述 | Dye-sensitized solar cells (DSSCs) are now able to enter in to the commercialization stage afterthe profound researches carried over the past two decade after their successful inception in 1991.Some of the possible reasons for the popularity are their low cost of production, short energypayback time (EPBT), simple methods of fabrication and possibilities of fabricating on theflexible substrates. Cost of the solar cell is an important factor in implementing the DSSC’s useat the mass consumer level having mainly three possible ways to decrease the overall cost. Oneapproach is to design the dyes with high molar extinction coefficient such as organic dyes or toincrease the absorption range of the dyes for example black dye, which increases the DSSCefficiency or output power. Second one is to increase the life-time of DSSC, which can be doneby improving the dye stability, proper sealing of DSSC and replacing the corrosive redoxelectrolyte. Third approach is to decrease the cost of materials implemented for DSSCfabrication such as designing the cheap dye material, removal of costly transparent conductiveoxide (TCO) and costly catalytic Pt etc. TCO glass is one of the expensive elements inconventional DSSC architecture. In this step, past researches for the removal of TCO have beendone. Back contact TCO-less DSSC using metal mesh have been reported by our group. Furtherthe back contact TCO-less cylindrical DSSC architecture was reported using metal mesh owingto advantage of uniform solar harvesting from all directions, higher total output power in a daycompared to flat conventional DSSC, easy to carry and install. The fabrication process involvedin the cylindrical DSSC is a bit cumbersome and need simplification for the commercialexploitation. Therefore, the goal of my current research was to develop a new cylindricalarchitecture for DSSC which could solve some of the previously existing problems in cylindricalDSSC architectures. In this report, I will discuss mainly the following points.(1) Different flexible metal wires such as Copper (Cu), Stainless-Steel (SS) and Titanium (Ti)were employed to fabricate the novel cylindrical DSSC and we gave it a name as coil typecylindrical DSSC (C-DSSC). The fabrication steps involved were fast and easy. We haveshown that the nature of the wire plays an important role on the performance of the solarcells. The effect of surface passivation on the metal wire surface with a thin layer of Tiwas discussed. Electrochemical Impedance spectroscopy (EIS) analyses were done toinvestigate about the differential performance of the solar cell using different metal wires.(2) Relatively lower resistance, good flexibility, superior corrosion resistance and hightemperature tolerance of Ti wire make it a better choice for C-DSSC. Here we presentedthe comparative study of the photovoltaic characteristics of the solar cells prepared withTi wires having different diameters. The Ti wire surface was modified using hydrogenperoxide (H2O2). This surface treatment have been found to influence the adhesion as wellas electrical contact between coated nanoporous titanium oxide (TiO2) and Ti-wires. Theresults were supported by X-ray diffraction (XRD), X-ray photoelectron spectroscopy(XPS) and scanning electron microscopy (SEM).(3) Diffused light performance is one of the application areas of DSSC where they canoutperform to their inorganic solar cell counterparts. In this part we investigated the 1SUN and low light intensity fluorescent light performance of Ti wire based C-DSSC usingruthenium based N719 dye and organic dyes such as D205 and Y123. The cylindricalgeometry gives an advantage above flat conventional DSSC i.e. it allows to use thereflectors to further enhance the output power. Therefore, we used different parabolicreflectors to tap diffused light for indoor applications. Effect of shape and size of thereflector geometry on the C-DSSC performance was also investigated. Optical simulationsoftware Trace Pro 7.5.1 was also used to analyze the spectral distribution on the TiO2surface. | |||||||
