Solar Energy: The Physics and Engineering of Photovoltaic Conversion, Technologies and Systems

This book uniquely covers both the physics of photovoltaic (PV) cells and the design of PV systems for real-life applications. - Fundamental principles of semiconductor solar cells. - PV technology: crystalline silicon solar cells; thin-film cells; PV modules; third-generation concepts. - PV systems, from simple stand-alone, to complex systems connected to the grid; components; design; deployment; performance. The book is an invaluable reference for researchers, industrial engineers and designers working in solar energy generation. The book is also ideal for university and third-level physics or engineering courses on solar photovoltaics, with exercises to check students' understanding and reinforce learning. It is the perfect companion to the Massive Open Online Course (MOOC) on Solar Energy (DelftX, ET.3034TU) presented by co-author Arno Smets. The course is available in English on the nonprofit open source edX.org platform, and in Arabic on edraak.org. Over 100,000 students have already registered for these MOOCs.

Mathematics for the Physical Sciences

Introduction to and use of complex analysis and algebraic techniques to understand the solution of boundary value problems. Physics examples serve to introduce the fundamental partial differential equations and "special functions" of mathematical physics. A thorough analysis of Green's functions leads to a discussion of integral equations. Supplementary topics include dispersion relations and rational function approximation.

Eating to win: activity, diet and weight control

What should we eat before and after exercise? This free course, Eating to win: activity, diet and weight control, examines the importance of nutrition in physical activity, sport and weight management. The role that physical activity has alongside nutrition in controlling body weight will be discussed, as will considerations for pre-exercise and post-exercise nutrition and hydration.
