Abstract

This Dissertation / Report is the outcome of investigation carried out by the creator(s) / author(s) at the department/division of Central Food Technological Research Institute (CFTRI), Mysore mentioned below in this page.

Item Type:	Student Project Report
Additional Information:	The solar electricity is presently a rapidly growing but often relatively expensive renewable energy form. Recently however, new molecular photovoltaic (PV) materials have been developed, which could enable a production of low-cost solar cells in the future. The report begins with a discussion of the current status of the PV technology and a short introduction to the different PV technologies and to the basics of photovoltaics. The dye-sensitized solar cell (DSSC) is an electrochemical solar cell where light absorption occurs by dye molecules attached to a nanostructured TiO2 electrode. An introduction to the DSSC is given including a short description of the operating principle of the cell and a discussion of the physical and chemical processes behind it. A systematic literature review is done on the materials and most essential preparation methods of the standard DSSC. The performance of the DSSC is reviewed in terms of the output voltage and stability. The important directions of development are the transition from glass substrates to plastic foils and from batch processing to continuous processing as well as the use of solid state electrolytes. The glass-based DSSC technology is on the verge of commercialization and the manufacturing cost estimates for the technology are close to the projected costs of other PV technologies. The application of different types of organic photovoltaic materials including semiconducting polymers, dyes, pigments and liquid crystalline materials was tested. A review is done on the performance results of organic solar cells categorizing the cells by voltage. The development of the organic PV materials is still at an early stage and no clearly outperforming materials or cell structures have yet emerged. Experimental results are reported including a demonstration of the dye-sensitization with a natural dye as well as a preparation and testing of a series of quantum dot based DSSCs.
