Current concerns regarding greenhouse gas-related environmental effects, energy security, and the rising costs of fossil fuel-based energy has renewed interest in solar energy in general and photovotaics in particular. Exploring state-of-the-art developments from a practical point of view, Nanotechnology for Photovoltaics examines issues in increasing efficiency, decreasing costs, and how these two goals can be achieved in a single photovoltaic device. It provides fundamental background and places research approaches within the proper physical context as related to photovoltaics performance enhancement. The book reviews the applications of devices and their performance requirements, followed by coverage of thin films and advanced band structure concepts for obtaining efficiencies above the Shockley-Queisser single bandgap efficiency limit of ~31%. The editor and contributors also discuss the basic optical properties of nanostructured materials as related to photovoltaics applications and describes nanoscale optoelectronic device physics related to performance. They then explore recent literature in the application of various classes of nanostructures to photovoltaics. The book covers solar cells based on hybrid organic-inorganic nanocomposites structures, quantum wells, nanowires/tubes, and quantum dots. It also discusses the use of nanoparticles/quantum dots to enhance the performance of conventional solar cells and luminescent solar concentrators. Each chapter summarizes the historical development for the nanostructure class under consideration, applications beyond photovoltaics, and the major synthetic methods, followed by a critique of leading works that have employed the particular nanostructure type. The book examines the advantages of each nanostructure approach and the remaining technical challenges, with an emphasis on possible future areas of research interest. It concludes with a summary of the major

This book combines the proceedings of Symposium P, The Business of Nanotechnology, and Symposium YY, Compatibility of Nanomaterials, both from the 2009 MRS Fall Meeting in Boston. Papers from Symposium P highlight the constructive disruption caused by the introduction of innovative and value-generating products based on nanotechnology, and underscore the intersections of scientific research and business considerations in the nanotechnology space. The section begins with papers on commercialization challenges in nanotechnology, and specific technologies are also discussed. The final papers in this section include applications of nanosensors for neonatal care, new oxygen sensors and nanocatalysts. Papers from Symposium YY focus on the impact on nanomaterials on health and safety topics that are also critical in the commercialization of nanotechnologies. Presentations bridge the gap between fundamental material science in nanomaterial design, fabrication, and characterization, and cover diversity in the field, from using nanomaterials to fight cancer, infection and regenerate tissues. Several papers also address nanoparticle toxicity. The beginnings of 'green nanotechnology' are also featured.
