The book focuses on dye-sensitized solar cells (DSSCs), which are considered to be highly efficient as they are made of low cost materials with simple and economical manufacturing procedures and can be molded into malleable sheets. These cells have emerged as a new class of energy conversion tools, which represent the third generation of solar technology. The method of converting solar energy into electricity in these devices is quite distinctive. The energy conversion efficiency produced by the DSSCs is low, but, it has upgraded quickly in the last years. It is assumed that the DSSCs will take an admirable place in the large scale production for the future. This book covers various aspects related to DSSCs such as photon management strategies, metal substrates, carbon nanostructures as low cost and DSSCs as an alternative approach.

The operation of everything in the universe needs a special „material“-energy. The earth is no exception. There are many kinds of energy sources on earth. But where does the earth‘s energy come from? The answer is that everything grows under the sun. Developing renewable energy is of strategic importance to achieve sustainable energy supply. Simulating natural photosynthesis is the ultimate goal of effi cient solar energy conversion. Photovoltaic technology has been widely used in industry and will be one of the major energy sources in the future. Developing new materials and structures, the photoelectric conversion effi ciency of solar cells will be improved day by day, and solar cells will attract more and more attention. This book presents principles of solar photovoltaic conversion, and introduces the physical and chemical processes involved. Mechanisms which affect solar cell performance are also discussed.
This book covers topics related to photovoltaic generations, its unique scientific ideas and technical solutions. Issues related to the capability of solar cells and the hydrogen productions in photoelectrochemical solar cells have also been discussed. Usage of advanced materials, like the oxide of copper as an active substance for solar cells, InP in solar cells with MIS arrangement, AlSb for use as an absorber layer, among others, have been discussed. Furthermore, other significant topics such as the analysis of both the status and prospects of organic photovoltaics such as polymer/fullerene solar cells, poly (p-phenylene-vinylene) derivatives, etc. have also been included.
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.

Volume is indexed by Thomson Reuters BCI (WoS).The development of photovoltaic technology is expected to solve problems related to energy shortages and environmental pollution caused by the use of fossil fuels. Dye-sensitizedsolar cells (DSSCs) are promising next-generation alternatives to conventional silicon-based photovoltaic devices owing to their low manufacturing cost and potentially high conversion efficiency. This special topic volume addresses recent advances in the research on dye-sensitized solar cells. The focus of this special topic volume is on materials development (sensitizers, nanostructured oxide films, and electrolyte), but commercialization. This work illustrates a new pathway to achieve highly efficient DSSCs for practical applications.
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.
