Free Download Jiangzhao Chen, "Handbook of Perovskite Solar Cells, Volume 3: Critical Challenges and Opportunities in Commercialization " English | ISBN: 1032509805 | 2024 | 192 pages | PDF | 18 MB Perovskite solar cells (PSCs) have emerged as one of the most promising new solar cells, with strong commercial potential. Several challenges remain before PSCs can be released in wide-scale commercial application. This book highlights the opportunities, advancements, and critical challenges involved in the commercial application of PSCs. It discusses large area fabrication, long-term stability, lead management, encapsulation techniques, as well as a commercial roadmap and current and future trends.  Free Download Jiangzhao Chen, "Handbook of Perovskite Solar Cells, Volume 2: Functional Layer Optimization and Diverse Device Types for Efficiency and " English | ISBN: 1032509694 | 2024 | 452 pages | PDF | 156 MB Perovskite solar cells (PSCs) have received significant attention in academia and industry due to their low cost and high-power conversion efficiency (PCE). Single- and multijunction PSCs have obtained promising certified PCEs, which suggests that PSCs are a very promising next-generation photovoltaic technology. In addition to the perovskite absorber layer, other functional layers, including electron transport layer (ETL), hole transport layer (HTL), and electrode layer (EL), have also made huge contributions to enhancing device performance. This book focuses on the development, advancement, and application of these functional layers in various PSCs.  Free Download Jiangzhao Chen, "Handbook of Perovskite Solar Cells, Volume 1: Fundamentals and Absorber Layer Optimization for Efficiency and Stability " English | ISBN: 1032509651 | 2024 | 440 pages | PDF | 89 MB Organic-inorganic hybrid metal halide perovskite materials have attracted significant attention due to their advantages of low cost, tunable band gap, solution processing, high molar extinction coefficient, low exciton binding energy, and high carrier mobility. Perovskite absorber layers play a decisive role in the realization of high-power conversion efficiency in perovskite solar cells (PSCs). This book systematically and comprehensively discusses device structures, working principles, and optimization strategies of perovskite absorber layers for PSCs to help foster commercialization of these environmentally friendly power sources. It describes strategies to optimize the quality of perovskite films, including composition engineering, dimensional engineering, solvent engineering, strain engineering, additive engineering, and interface engineering.

A leading well-being educator empowers you to turn concepts like boundaries and self-care into practical rituals with the power to transform your life.  Free Download Samuel C. Sugarman, "HVAC Fundamentals: System Design, Operation, Selection, and Optimization Ed 4" English | ISBN: 877004144X | 2024 | 514 pages | PDF | 28 MB HVAC Fundamentals, System Design, Operation, Selection, and Optimization fully covers the full range of HVAC systems used in today's facilities and how they operate. HVAC systems are divided into components and controls for air, water, heating, ventilating and air conditioning to illustrate how each system, subsystem, control, or component contributes to providing the desired indoor environment. The reader will learn why one component or system may be chosen over another with respect to design, application, energy conservation, indoor air quality, and cost.  Free Download HTML5 Handbuch By Stefan Münz, Clemens Gull 2013 | 800 Pages | ISBN: 3645602844 | PDF | 8 MB HTML5 ist die Sprache des Web. Und das HTML5-Handbuch von Stefan Münz und Clemens Gull ist die Grammatik dazu. Wie einst die von Stefan Münz mitbegründete Onlinereferenz SELFHTML beantwortet dieses Buch alle Fragen zum neuen Internetstandard. Immer wichtiger wird dabei die Ausgabe auf Smartphones und Tablets, deshalb ist diesem Thema hier ein eigenes Kapitel gewidmet. Das unverzichtbare Standardwerk für jeden Webprofi!  Free Download Oswald Campesato, "HTML 5 Pocket Primer" English | ISBN: 1938549104 | 2013 | 200 pages | EPUB, MOBI | 26 MB + 36 MB As part of the new Pocket Primer series, this book provides an overview of the major aspects, the source code, and tutorial videos to use HTML5. DVD with code, videos, and graphics included.  Free Download Nazeih Botros, "HDL with Digital Design " English | ISBN: 1938549813 | 2015 | 750 pages | MOBI | 18 MB This book introduces the latest version of hardware description languages and explains how the languages can be implemented in the design of the digital logic components. In addition to digital design, other examples in the areas of bioengineering and basic computer design are covered. Unlike the competition, HDL with Digital Design introduces mixed language programming. By covering both Verilog and VHDL side by side, students, as well as professionals, can learn both the theoretical and practical concepts of digital design. The two languages are equally important in the field of computer engineering and computer science as well as other engineering fields such as simulation and modeling.
