Book Description :

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.

Book Description :

Renewable energies have become an attractive option to overcome the energy demands in sustainable and affordable ways. It has been estimated that one-third of the total renewable energies would be generated from photovoltaics (PVs). A solar or PV cell is a device that directly converts sunlight into electricity by taking benefit of the photoelectric effect. In the third-generation solar PVs, dye-sensitized solar cells (DSSCs) are believed to be the most promising and have attracted wide attention. The optimization of a DSSC is focused on four main components: (i) metal oxide semiconductor, (ii) photosensitizer, (iii) redox couple electrolyte, and (iv) counter electrode. Among these, the counter electrode undertakes three functions: (i) as a catalyst, (ii) as a positive electrode of primary cells, and (iii) as a mirror. To obey these functions, the electrode material should have high catalytic activity, high conductivity, high reflectivity, high surface area, and electrochemical and mechanical stability. To improve the performance of DSSCs, many scientists have developed new counter electrodes made of platinum, carbon materials, transition metals, conductive polymers, and composites. This book converses the various aspects of materials for the fabrication of counter electrodes especially for the DSSCs.

Book Description :

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.

Book Description :

The second book of the four-volume edition of "Solar cells" is devoted to dye-sensitized solar cells (DSSCs), which are considered to be extremely promising because they are made of low-cost materials with simple inexpensive manufacturing procedures and can be engineered into flexible sheets. DSSCs are emerged as a truly new class of energy conversion devices, which are representatives of the third generation solar technology. Mechanism of conversion of solar energy into electricity in these devices is quite peculiar. The achieved energy conversion efficiency in DSSCs is low, however, it has improved quickly in the last years. It is believed that DSSCs are still at the start of their development stage and will take a worthy place in the large-scale production for the future.

Book Description :

A breath of fresh Dye-Sensitized Solar Cells air. In the belated 1960s it was ascertained that lighted biological colors may create power at oxide electrodes in electrochemical cells. In an attempt to comprehend and imitate the main actions in photosynthesis the occurrence was learned at the University of California at Berkeley with chlorophyl taken out as of spinach (bio-mimetic either Bionic approach). On the base of such trials galvanic power propagation by way of the color sensitisation solar cell (DSSC) concept was revealed and deliberated in 1972. The unstableness of the color solar cell was recognized like a principal dare. Its effectiveness might, throughout the ensuing 2 periods of ten years, be ameliorated by enhancing the absorbency of the electrode readied as of great oxide dust, however the unstableness stayed a difficulty. A contemporary DSSC is devised of a porous level of titanium dioxide nanoparticles, veiled with a molecular color that soaks up sunshine, like the chlorophyl in green departs. The titanium dioxide is submerged under an electrolyte resolution, overhead that is a platinum-based accelerator. As in a normal alkaline cell, an anode (the titanium dioxide) and a cathode (the platinum) are put on whichever aspect of a fluid conductor (the electrolyte).

Book Description :

Dye-sensitized solar cells (DSCs) offer a variety of advantages to typical silicon and thin film solar cells. And while the advantages of ease-of-processing and fabrication from low-cost, earth-abundant materials make DSCs an attractive technology, the efficiency of DSCs (13%) is still too low to compete with the current inorganic incumbents. Hence, new 'outside-of-the-box' strategies must be used to render DSCs competitive with current commercial technologies. This thesis describes my work on identifying losses in DSCs and 2 strategies to improve the efficiency of DSCs: the use of highly-soluble energy relay days to broaden the spectral response of DSCs, and the fabrication of semi-transparent solid-state DSCs to help improve the efficiency of inorganic devices in a tandem solar cell. Solid-state dye-sensitized solar cells (ssDSCs) have historically lagged behind their liquid-electrolyte counterparts in efficiency. To gain a better understanding of why this is so, we have developed accurate internal quantum efficiency (IQE) measurements for ssDSCs. By analyzing the IQE, it is found that while charge collection is efficient in ssDSCs, often charge injection is not. This analysis also shows that parasitic absorption by the Spiro-OMeTAD is an important loss mechanism in ssDSCs and suggests that stronger absorbing sensitizers are the most promising path to higher efficiencies. In DSCs, the roles of absorbing light, injecting charge, and blocking recombination are all given to the sensitizing dye, resulting in a myriad of design rules for DSC sensitizers. An energy relay dye (ERD) is a second dye that helps relax these design rules by providing complementary absorption and then transferring energy to a sensitizing dye. However, such ERDs come with their own design rules, including the need for high solubility for full light absorption, and high photoluminescence for efficient energy transfer. We have designed and synthesized two such dyes, and characterized them as ERDs in DSCs, yielding a 65% increase in efficiency. Finally, even if DSCs are unable to reach efficiencies that render them competitive against traditional inorganic solar cells, DSCs can be used in conjunction with an inorganic solar cell in a hybrid tandem photovoltaic (HTPV). High open-circuit voltages and cheap processing render DSCs attractive top cells in HTPVs, and such devices can exceed efficiencies of 20%. However, in order to be used in HTPVs, a DSC must be fabricated such that below bandgap light can pass through the device and be absorbed by the inorganic bottom cell. Toward that end, we have developed a transparent top contact for solid-state dye-sensitized solar cells that renders ssDSCs attractive candidates for HTPVs.
