The dye-sensitized solar cell (DSC) is a photovoltaic converter that mimics natural photosynthesis. Like green plants and algae it uses a molecular absorber, the dye, to harvest sunlight and generate electric charges. Dye-sensitized solar cells are poised to replace existing technologies in «low density» solar-energy applications, especially in contexts where mechanical robustness and light weight is required. This book offers the first comprehensive look at this promising technology and aims to provide a graduate level text that brings together the fundamentals of DSC from three perspectives (materials, performance, and mechanistic aspects), as well as to serve as an advanced monograph that summarizes the key advances and lists the technical challenges remaining to be solved.

The global energy consumption has been increasing at an alarming rate over the years. In 1998, it was 12.7TW, but in 2050, it is expected to be around 26.4 to 32.9TW and in 2100, it will increase up to 46.3 to 58.7TW. The yearly increase in global energy consumption is expected to result in the rise of demands towards natural resources such as coal, petroleum and natural gas. Since these natural resources take thousands of years to form, it is impossible to replace them in the same rate at which they are being consumed. Therefore, it is a well-known fact that with the shortage of resources there will be an unprecedented rise in the harvesting expenses. Hence, the reliability on the other sources of energy, which are renewable will rise. In the current scenario solar cells, which are also known as photovoltaic cell seem to be one of the promising options of renewable energy.The very first cohort of photovoltaic cells were constructed using crystalline silicon disks. The next batch was primarily built using semiconductors. These semiconductors were usually compounds of III-V type, like cadmium telluride and copper indium selenide/sulphide. The dye-sensitized solar cells (DSSC) which belong to the thin film group, emerged as a new class of low cost energy conversion devices with simple manufacturing procedures. Incorporation of dye molecules in some wide bandgap semiconductor electrodes was a key factor in developing photoelectrochemical solar cells with improved efficiency.In this book, we begin with a detailed explanation about the basics of solar cell technology and move on to overview some aspects of the historical background, present-scenario, currently popular applications and future prospects of dye sensitized solar cells. The structural aspects and working principle of this promising class of solar cells has been dealt in detail for providing a good understanding of the basics. Some novel schemes in preparation and assembly of dye sensitized solar cell have been presented from recent literature reports. The performance of nanocrystalline solar cell samples can be appreciably improved by optimizing the preparation technique, the class of the nanostructured materials, types of electrolyte, and high transparent conductive electrodes. Challenges associated with materials choice, nanostructured electrodes and device layers structure design are detailed. Recent trends in the development of nano-crystalline materials for DSSCs technology are introduced. Manufacturability and different approaches suggested for commercialization of DSSC for various applications are outlined and discussed in detail.

This book contains chapters in which the problems of modern photovoltaics are considered. The majority of the chapters provide an overview of the results of research and development of different types of solar cells. Such chapters are completed by a justification for a new solar cell structure and technology. Of course, highly effective solar energy conversion is impossible without an in-depth examination of the solar cell components as physical materials. The relations between structural, thermodynamic, and optical properties of the physical material without addressing the band theory of solids are of both theoretical and practical interest. Requirements formulated for the material are also to be used for maximally efficient conversion of solar radiation into useful work.

Dye-sensitized solar cell (DSSC) is one of the emerging thin-film photovoltaic technologies. Advantages come from the low cost and easier fabrication process. The realistic overall conversion efficiency already made the commercial availability a reality. It is possible the use of natural dyes extracted from plants in DSSC fabrication to substitute synthetic dyes, which requires complex fabrication processes and the use of toxic and scarce materials, like ruthenium. Natural dye-sensitized solar cells (NDSSC) are still in an early stage, with many research groups working hard to overcome efficiency and stability issues. Natural dyes are cheap, highly available, environmentally safe and easy to extract. Nature has so much to offer to humankind, each plant is unique, with characteristics developed during million of years of evolution. Each biome has an enormous number of species readily available for study. Among them, Brazilian forests are in an outstanding position, with a gigantic quantity of species with hidden opportunities. This work aims to inspire other researchers to explore this field and find in nature new answers for a clean energy demanding world. It is shown the basic aspects of NDSSC study and practical research, from laboratory construction to cells fabrication. After a brief introduction about PV technologies, DSSC is deeper discussed based on a literature review. Physical and electrochemical aspects are presented in details. Natural dyes specificities and application in DSSC are then discussed also based on other researchers findings. With a well-established theoretical basis, this work focus then on the development of a NDSSC fabrication protocol, presenting the most important tests and results achieved. A special highlight is given to the design and fabrication of a solar simulator from scratch. Having the infrastructure, equipments and protocol defined, the fabrication of NDSSC based on Brazilian plants was possible, including plants naturally originated in the country: blackberry, quaresmeira and embaúba-vermelha, and two other non-native species due to their economically important role, of which Brazil is currently the world leader producer, they are: arabica coffee and sugarcane. The found cells efficiencies for all studied plants dyes are in the range of other important research publications, even for the simplified and low cost proposed protocol, which validates the solutions and techniques used. Coffea arabica (arabica coffee) provided the best performance, reaching 0.44% overall conversion efficiency, with no special commonly used chemical treatment, co-adsorbent or purification, such as: TiCl4, organic acids, chromatography and lyophilization. It is hoped this work contribute for the development of an even greener energy generation from sunlight.

A dye-sensitized solar cell (DSSC, DSC or DYSe is a relatively new class of low-cost solar cell, that belong to the group of Thin film solar cells. It is based on a semiconductor formed between a photo-sensitized anode and an electrolyte, a photoelectrochemical system. This cell was invented by Michael Grtzel and Brian O'Regan at the cole Polytechnique Fdrale de Lausanne in 1991 and are also known as Grtzel cells. This cell is extremely promising because it is made of low-cost materials and does not need elaborate apparatus to manufacture. In bulk it should be significantly less expensive than older solid- state cell designs.

With the worldly consumption of energy continually increasing and the main source of this energy, fossil fuels, slowly being depleted, the need for alternate sources of energy is becoming more and more pertinent. One promising approach for an alternate method of producing energy is using solar cells to convert sunlight into electrical energy through photovoltaic processes. Currently, the most widely commercialized solar cell is based on a single p-n junction with silicon. Silicon solar cells are able to obtain high efficiencies but the downfall is, in order to achieve this performance, expensive fabrication techniques and high purity materials must be employed. An encouraging cheaper alternative to silicon solar cells is the dye-sensitized solar cell (DSSC) which is based on a wide band gap semiconductor sensitized with a visible light absorbing species. While DSSCs are less expensive, their efficiencies are still quite low compared to silicon. In this thesis, Grätzel cells (DSSCs based on TiO2 NPs) were fabricated and optimized to establish a reliable standard for further improvement. Optimized single layer GSCs and double layer GSCs showing efficiencies>4% and efficiencies of ~6%, respectively, were obtained. Recently, the incorporation of metallic nanoparticles into silicon solar cells has shown improved efficiency and lowered material cost. By utilizing their plasmonic properties, incident light can be scattered, concentrated, or trapped thereby increasing the effective path length of the cell and allowing the physical thickness of the cell to be reduced. This concept can also be applied to DSSCs, which are cheaper and easier to fabricate than Si based solar cells but are limited by lower efficiency. By incorporating 20 nm diameter Au nanoparticles (Au NPs) into DSSCs at the FTO/TiO2 interface as sub wavelength antennae, average photocurrent enhancements of 14% (maximum up to ~32%) and average efficiency enhancements of 13% (maximum up to ~23%) were achieved with well dispersed, low surface coverages of nanoparticles. However the Au nanoparticle solar cell (AuNPSC) performance is very sensitive to the surface coverage, the extent of nanoparticle aggregation, and the electrolyte employed, all of which can lead to detrimental effects (decreased performances) on the devices.
