Book Nickel Silicide as a Contact and Diffusion Barrier for Copper Metallization in Silicon Photovoltaics

Download or read book Nickel Silicide as a Contact and Diffusion Barrier for Copper Metallization in Silicon Photovoltaics written by Alexander Angus Marshall and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "In this study, NiSi has been formed as the contact for copper front metallization on laboratory silicon solar cells. Transfer length method (TLM) measurements were used to examine the resistive nature of the contact. The scalability of the measurement itself was also examined. Characterization of the NiSi films for thickness, resistivity and composition were performed. Single crystal silicon solar cells were fabricated and used in temperature stress tests of the degradation of the pseudo-fill factor (pFF) and quantum efficiency (QE) to assess the capabilities of the NiSi diffusion barrier. Best contact resistivities of 7.3e-6 Ohm-cm2 with NiSi only and 4.0e-5 Ohm-cm2 with NiSi/Cu/TiN were measured. Even following a week of temperature stress, NiSi maintained solar cell performance parameters such as pseudo fill factor (pFF) and quantum efficiency (QE) better than Cu/TiN contacts without NiSi and at least as good as Ti/Pd/Ag contacts on average. These methods and materials were applied to high efficiency, textured, solar cells with passivated tunneling contacts. The viability of NiSi in this regime was evaluated by photoluminescence (PL), optical, and TLM measurements. Although the NiSi contact was shown to damage the passivation quality of the contact, a cell capable of an open circuit voltage near 700 mV could be produced using such a contact scheme. Contact resistances as low as 1.8 mOhm-cm2 were formed, as compared with industry standard screen printed Ag contacts which form best contact resistivities in the range of 1.5 mOhm-cm2."--Abstract.

Book Nickel Silicide Contact for Copper Plated Silicon Solar Cells

Download or read book Nickel Silicide Contact for Copper Plated Silicon Solar Cells written by Harsh Narendrakumar Jain and published by . This book was released on 2016 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nickel-Copper metallization for silicon solar cells offers a cost effective alternative to traditional screen printed silver paste technology. The main objective of this work is to study the formation of nickel silicide contacts with and without native silicon dioxide SiO2.The effect of native SiO2 on the silicide formation has been studied using Ramanspectroscopy, Rutherford backscattering spectrometry and sheet resistancemeasurements which shows that SiO2 acts as a diffusion barrier for silicidation at low temperatures of 350°C. At 400°C the presence of SiO2 results in the increased formation of nickel mono-silicide phase with reduced thickness when compared to samples withoutany native oxide. Pre and post-anneal measurements of Suns Voc, photoluminescence and Illuminated lock in thermography show effect of annealing on electrical characteristics of the device. The presence of native oxide is found to prevent degradation of the solar cells when compared to cells without any native oxide. A process flow for fabricating siliconsolar cells using light induced plating of nickel and copper with and without native oxide(SiO2) has been developed and cell results for devices fabricated on 156mm wafers have been discussed.

Book Silicide Formation and the Interaction of Metals with Polycrystalline Si

Download or read book Silicide Formation and the Interaction of Metals with Polycrystalline Si written by Johnson Olufemi Olowolafe and published by . This book was released on 1977 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main factors affecting solid-phase Si-metal interactions are reported in this work. The influence of the orientation of the Si substrates and the presence of impurities in metal films and at the Si-metal interface on the formation of nickel and chromium silicides have been demonstrated. We have observed that the formation and kinetic rate of growth of nickel silicides is strongly dependent on the orientation and crystallinity of the Si substrates; a fact which, up to date, has never been seriously investigated in silicide formation. Impurity contaminations in the Cr film and at the Si-Cr interface are the most dominant influencing factors in the formation and kinetic rate of growth of CrSi2. The potentiality and use of silicides as a diffusion barrier in metallization on silicon devices were also investigated.

Book Silicon Heterojunction Solar Cells

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 208 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.

Download or read book Solar Cells written by Leonid A. Kosyachenko and published by BoD – Books on Demand. This book was released on 2015-10-22 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
