Available in PDF, EPUB and Kindle. Book excerpt: Reduction of optical losses in both mono and multicrystalline silicon solar cells by surface texturing is one of the important issues of modern silicon photovoltaics. Texturing of the front surface of silicon solar cells has been modeled and analysed with reference to the reduction in reflection co-efficient and increase in optical trapping. Significant enhancement in open circuit voltage and short circuit current has been achieved through such texturing of the front surface of mono-silicon solar cells. A proper optimisation of texture angle appears to be important for the best performance of the solar cells. An alternative way of reducing the surface reflection and enhancement of the cell parameters is to produce to passive front surface porous silicon layer. An analysis of the characteristics of a porous silicon layer shows that the morphology of the layer is an important design parameter. To realise the structures in practice, several methods are available, but many of this method are either not cost effective or commercially non available. In order to achieve good uniformity of pyramidal textured structure of the silicon surface, a mixture of NaOH/KOH and isopropyl alcohol (IPA) is generally used for texturization of mono crystalline solar cells. However, due to high cost of IPA, there is always search for alternative source. This source should not only be cost effective but should also result in reduced interfacial energy between silicon and ionised electrolyte chemical solution to achieve sufficient wet-ability for the silicon surface in order to enhance pyramid nucleation. Different novel texturization techniques for monocrystalline silicon are descried in this chapter including solar cells performance. For multicrystalline silicon (mc-Si) solar cells, the standard alkaline solution of NaOH/KOH does not produced textured surface of good quality so as to give satisfactory open circuit voltage and efficiency. This is because of grain boundary delineation with step formed between successive grains of different orientations. Different novel texturization techniques for multicrystalline silicon are also included in this book including solar cells performance.

Book Synopsis Solar Cell Research Progress by : Joseph A. Carson
Download or read book Solar Cell Research Progress written by Joseph A. Carson and published by Nova Publishers. This book was released on 2008 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: A solar cell or photovoltaic cell is a device that converts light energy into electrical energy. Sometimes the term solar cell is reserved for devices intended specifically to capture energy from sunlight, while the term photovoltaic cell is used when the light source is unspecified. Fundamentally, the device needs to fulfil only two functions: photogeneration of charge carriers (electrons and holes) in a light-absorbing material, and separation of the charge carriers to a conductive contact that will transmit the electricity (simply put, carrying electrons off through a metal contact into a wire or other circuit). This conversion is called the photovoltaic effect, and the field of research related to solar cells is known as photovoltaics. Solar cells have many applications. They have long been used in situations where electrical power from the grid is unavailable, such as in remote area power systems, Earth-orbiting satellites and space probes, consumer systems, e.g. handheld calculators or wrist watches, remote radiotelephones and water pumping applications. More recently, they are starting to be used in assemblies of solar modules (photovoltaic arrays) connected to the electricity grid through an inverter, often in combination with a net metering arrangement. This new book presents the latest research in the field from around the globe.
Book Synopsis Thin-Film Silicon Solar Cells by : Arvind Shah
Download or read book Thin-Film Silicon Solar Cells written by Arvind Shah and published by EPFL Press. This book was released on 2010-08-19 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photovoltaic technology has now developed to the extent that it is close to fulfilling the vision of a "solar-energy world," as devices based on this technology are becoming efficient, low-cost and durable. This book provides a comprehensive treatment of thin-film silicon, a prevalent PV material, in terms of its semiconductor nature, starting out with the physical properties, but concentrating on device applications. A special emphasis is given to amorphous silicon and microcrystalline silicon as photovoltaic materials, along with a model that allows these systems to be physically described in the simplest manner possible, thus allowing the student or scientist/engineer entering the field of thin-film electronics to master a few basic concepts that are distinct from those in the field of conventional semiconductors. The main part of the book deals with solar cells and modules by illustrating the basic functioning of these devices, along with their limitations, design optimization, testing and fabrication methods. Among the manufacturing processes discussed are plasma-assisted and hot-wire deposition, sputtering, and structuring techniques.
Book Synopsis Silicon Heterojunction Solar Cells by : W.R. Fahrner
Download or read book Silicon Heterojunction Solar Cells written by W.R. Fahrner and published by Trans Tech Publications Ltd. This book was released on 2006-08-15 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world of today must face up to two contradictory energy problems: on the one hand, there is the sharply growing consumer demand in countries such as China and India. On the other hand, natural resources are dwindling. Moreover, many of those countries which still possess substantial gas and oil supplies are politically unstable. As a result, renewable natural energy sources have received great attention. Among these, solar-cell technology is one of the most promising candidates. However, there still remains the problem of the manufacturing costs of such cells. Many attempts have been made to reduce the production costs of “conventional” solar cells (manufactured from monocrystalline silicon using diffusion methods) by instead using cheaper grades of silicon, and simpler pn-junction fabrication. That is the ‘hero’ of this book; the heterojunction solar cell.
