The third generation of solar cells includes those based on semiconductor quantum dots. This sophisticated technology applies nanotechnology and quantum mechanics theory to enhance the performance of ordinary solar cells. Although a practical application of quantum dot solar cells has yet to be achieved, a large number of theoretical calculations and experimental studies have confirmed the potential for meeting the requirement for ultra-high conversion efficiency. In this book, high-profile scientists have contributed tutorial chapters that outline the methods used in and the results of various quantum dot solar cell designs, including quantum dot intermediate band solar cells, hot electron quantum dot solar cells, quantum-dot sensitized solar cells, colloidal quantum dot solar cells, hybrid polymer-quantum dot solar cells, and MEG quantum dot solar cells. Both theoretical and experimental approaches are described. Quantum Dot Solar Cells helps to connect the fundamental laws of physics and the chemistry of materials with advances in device design and performance. The book can be recommended for a broad audience of chemists, electrical engineers, and materials scientists, and is suitable for use in courses on materials and device design for advanced and future optoelectronics.

This book can be roughly divided into three parts: fundamental physico-chemical and physical principles of Nanoscience, chemistry and synthesis of nanoparticles, and techniques to study nanoparticles. The first chapter is concerned with the origin of the size dependence of the properties of nanomaterials, explaining it in terms of two fundamental nanoscale effects. This chapter also serves as a general introduction to the book, briefly addressing the definition and classification of nanomaterials and the techniques used to fabricate and study them. Chapter 2 lays out the theoretical framework within which to understand size effects on the properties of semiconductor nanocrystals, with particular emphasis on the quantum confinement effect. The optical properties of metal nanoparticles and metal nanostructures (periodic lattices) are discussed in Chapter 3. Chapter 4 is devoted to nanoporous materials, treating in detail their synthesis, structure and functional properties, as well as the physical properties of liquids confined in nanopores. The preparation methods, characterization techniques, and applications of supported nanoparticles are covered in Chapter 5. The sixth Chapter presents the essential physical-chemical concepts needed to understand the preparation of colloidal inorganic nanoparticles, and the remarkable degree of control that has been achieved over their composition, size, shape and surface. The last four Chapters are dedicated to a few selected characterization techniques that are very valuable tools to study nanoparticles. Chapter 7 concentrates on electron microscopy techniques, while Chapter 8 focuses on scanning probe microscopy and spectroscopy. Electron paramagnetic resonance (EPR) based spectroscopic techniques and their application to nanoparticles are explored in Chapter 9. Finally, Chapter 10 shows how solution Nuclear Magnetic Resonance (NMR) spectroscopic techniques can be used to unravel the surface chemistry of colloidal nanoparticles.

Abstract: Colloidal quantum dots (QDs) synthesized in versatile, easy-to-process solutions are opening up exciting prospects in multiple areas, especially in biomedical imaging, photovoltaics, solid-state lighting and displays. The success of most of these prospects relies on high-quality heterostructures that improve optical properties. In particular, the core/shell heterostructure with a type I straddling band offset has been indispensable but the applicability is often limited to those exploiting only photoluminescence. QDs and their heterostructures can also be made with anisotropic shapes that allow access to essentially an unlimited number of combinations of size, shape and composition. Structures that allow enhancement of optical properties and physical accessibility for carrier injection/extraction simultaneously can open up new and exciting prospects in photovoltaics and optoelectronics. This topical review focuses on nanorod-based colloidal semiconductor heterostructures. Two-component, type II staggered band offset nanorod heterostructures capable of efficiently separating photoinduced charges are first discussed. Double heterojunction nanorods that contain three different phases are then considered with respect to their novelty and potential as emissive materials in light-emitting diodes. We conclude with an outlook on the possibility of developing colloidal nanorods that contain epitaxial interfaces beyond the conventional semiconductor heterojunctions.
