This book was released on 2015 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our work was inspired by the need to improve the efficiency of new types of solar cells. We mainly focus on metal-semiconductor interfaces. In the CdSe study, we find that not all surface states serve to pin the Fermi energy. In our organic-metal work, we explore the complexity and challenges of modeling these systems. For example, we confirm that aromatic compounds indeed have stronger interactions with metal surfaces, but this may lead to the geometry changing as a result of the interaction. We also find that molecules that are not rigid are strongly affected by their neighboring molecules. Surface roughness will have an effect on molecules that more strongly bind to metal surfaces. This study of interfaces relates to one part of the picture of efficiency, but we also look at trying to go beyond the Shockley-Quiesser limit. We explore the idea of combining a direct and indirect bandgap in a single material but find that, in quasi-equilibrium, this does no better than just the direct gap material. This thesis hopes to extend our understanding of metal-semiconductor interface behavior and lead to improvements in photovoltaic efficiency in the future.

This book was released on 2017-07-12 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perovskites are a class of recently discovered crystals with a multitude of innovative applications. In particular, a lead role is played by organic-inorganic halide perovskites (OIHPs) in solar devices. In 2013 Science and Nature selected perovskite solar cells as one of the biggest scientific breakthroughs of that year. This book provides the first comprehensive account of theoretical aspects of perovskite solar cells, starting at an introductory level but covering the latest cutting-edge research. Theoretical Modeling of Organohalide Perovskites for Photovoltaic Applications aims to provide a theoretical standpoint on OIHPs and on their photovoltaic applications, with particular focus on the issues that are still limiting their usage in solar cells. This book explores the role that organic cations and defects play in the material properties of OIHPs and their effects on the final device, in addition to discussing the electric properties of OIHPs; the environmentally friendly alternatives to the use of lead in their structural and electronic properties; theoretical screening for OIHP-related material for solar-to-energy conversion; and the nature and the behavior of quasiparticles in OIHPs.

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 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.
