The first book of this four-volume edition is dedicated to one of the most promising areas of photovoltaics, which has already reached a large-scale production of the second-generation thin-film solar modules and has resulted in building the powerful solar plants in several countries around the world. Thin-film technologies using direct-gap semiconductors such as CIGS and CdTe offer the lowest. The II-IV semiconductor compound, CdTe, has suitable electrical and optical properties as photovoltaic and high-energy radiation sensor material. As an absorber material for thin-film-based solar cells, CdTe holds the potentiality to fabricate high-efficiency solar cells by means of low-cost technologies. This chapter presents a comprehensive review on the CdTe thin-film deposition techniques.
Amorphous Silicon Thin Film Solar Cell Scribing Photovoltaic device technology is a large beneficiary of increasing investment in alternative energy solutions. With manufacturing advantages such as scalability and cross-compatibility with the flat panel display industry, and with considerations for potential scarcity of silicon. The first part of the book covers hydrogenated amorphous silicon type alloys, whose applications include inexpensive solar cells, thin film transistors, image scanners, electrophotography, optical recording, and gas sensors. The second part of the book discusses amorphous chalcogenides, whose applications include electrophotography, switching.
Thin film solar cells (TFSC) are a promising approach for terrestrial and space photovoltaics and offer a wide variety of choices in terms of the device design and fabrication. Thin-film silicon solar panels are produced by forming an amorphous silicon (a-Si) film on a glass substrate. Similar to crystalline solar cells, or modules, the a-Si, photovoltaic panels are made from silicon, however, the amount of silicon required is very small: that is, one hundredth or less the amount of the crystalline photovoltaic cells (made from bulk silicon), since only a thin layer.

High-purity monocrystalline silicon has a long history in the development of photovoltaics; so far, it has dominant applications in modern computers with its profound implementations in transistors and chips.
The success of silicon has shown that monocrystalline wafers/thin films of semiconducting materials Recent Review Articles Journal of Materials Chemistry A HOT PapersCited by: 2.
Thin-film PV technologies, such as amorphous silicon, hold the promise for low cost.2 Of the thin-film technologies, amorphous silicon is the most mature" Other thin film technologies have promise, but their manufacturing process yields and costs have not yet been proven. It might take some time to do so.
At the present time hydrogenated amorphous silicon (a-Si:H) is a mature material of the microelectronics and photovoltaic industries. Its success is due to the compatibility with the silicon CMOS technology, the possibility of doping (n or p type), the low substrate temperatures used (≤°C) when is deposited by the plasma-enhanced chemical vapor deposition (PECVD) technique, and the Cited by: 1.
1. Introduction. Thin films of amorphous-nanocrystalline silicon (a-nc-Si) are a promising material for photovoltaic applications in new generation of solar cells.Due to good optical and electrical properties, a-nc-Si represents a promising replacement for amorphous silicon (a-Si) in low cost thin film silicon solar cells.
KEYWORDS amorphous silicon, CVD, XPS, depth profiles, photovoltaic, solar cells, stainless steel, substrate. INTRODUCTION A variety of methods are used to produce thin films of amorphous silicon but the glow discharge process is most favoured by manufacturers at the present time.
See for example Stuke (). How to Make an Amorphous Silicon Solar Cell. Although various techniques may be used, one way to produce a thin film amorphous silicon solar cell starts with a substrate. This is a thin sheet of plastic. Amorphous silicon is deposited as a vapor on one side and a very thin metal layer is placed on the other.
A.E. Dixon, in Solar Energy Conversion II, Amorphous Silicon Cells. Amorphous silicon solar cells are normally prepared by glow discharge, sputtering or by evaporation, and because of the methods of preparation, this is a particularly promising solar cell for large scale fabrication.
Because only very thin layers are required, deposited by glow discharge on substrates of glass or. Milton Ohring, in Materials Science of Thin Films (Second Edition), DEPOSITION AND STRUCTURE OF AMORPHOUS SILICON FILMS.
Amorphous silicon (a-Si) and hydrogenated versions of it, e.g., a-Si:H, are the basic materials discussed in this section. They have been deposited by both PVD and CVD techniques. Of the elements, silicon and others in column IV of the periodic table.
cells. Two different forms of silicon, pure silicon and amorphous silicon are used to build the cells. However, the use of the photovoltaic cells has been limited due to high processing cost of high purity single crystal material used and the lack of effective mass production techniques used to produce thin silicon films.

One new approach is based on a stack of two silicon thin-film cells, one cell using amorphous silicon and the other mixed-phase microcrystalline silicon.
NEW GENERATION PHOTOVOLTAIC TECHNOLOGIES T. Surek and R.D. McConnell Solar Energy Research Institute Cole Boulevard Golden, ColoradoU.S.A. ABSTRACT Five generations of photovoltaic technologies are identified: Single Crystal Silicon, Polycrystalline Silicon, Ribbon Silicon, Single-Junction Thin Films, and Multijunction Thin Films.
Recently plasmonic effects have gained tremendous interest in solar cell research because they are deemed to be able to dramatically boost the efficiency of thin-film solar cells. However, despite of the intensive efforts, the desired broadband enhancement, which is critical for real device performance improvement, has yet been achieved with simple fabrication and integration methods.

A major update of solar cell technology and the solar marketplace. Since the first publication of this important volume over a decade ago, dramatic changes have taken place with the solar market growing almost fold and the U.S. moving from first to fourth place in the world market as analyzed in this Second Edition.
Different bandgap engineering approaches are discussed with respect to their application in thin-film solar cells based on hydrogenated amorphous silicon (a-Si: H) and its alloys with Ge or C. Amorphous silicon (a-Si) is the non-crystalline form of silicon used for solar cells and thin-film transistors in LCDs.
Used as semiconductor material for a-Si solar cells, or thin-film silicon solar cells, it is deposited in thin films onto a variety of flexible substrates, such as glass, metal and plastic.
Amorphous silicon cells generally feature low efficiency, but are one of the most. Several aspects of the science and technology of thin film silicon for photovoltaic applications will be presented.
The potential advantages of this technology over crystalline wafer technology will be discussed. A basic understanding of the material properties of thin film silicon layers enables to assess their potential and limitations when used in photovoltaic devices.
Direct current magnetron sputtering was evaluated as a viable approach to producing amorphous SiH thin films for solar photovoltaic applications. It is shown that the optical and transport properties of these films are similar to those of rf diode sputtered material, but the photoresponse and, more importantly, Schottky diode performance are inferior to that already obtained by rd diode.Downloadable (with restrictions)!
