This book covers the recent advancements in the fabrication of flexible optoelectronic devices using advanced nanomaterials. It provides information on how to process non-layered advanced nanomaterials such as carbon nanotubes, fullerenes, nanowires, colloidal quantum dots, inorganic halide perovskite, perovskite nanomaterials stabilized in porous materials, doped-ZnO, lead chalcogenide nano crystals for the easy fabrication of the optoelectronic devices at an industrial scale. Advanced Nanomaterials for Solution-Processed Flexible Optoelectronic Devices provides up-to-date knowledge centered on the various non-layered nanomaterials and their different types of application in optoelectronic device fabrication. The first few chapters focus on the processing and applications of carbon nanotubes and fullerenes into devices for photovoltaics. Throughout the book the authors demonstrate not only device fabrication but processing of the advanced nanomaterials to make them suitable for wide applications as different components in optoelectronics. The book also presents discussions on the current challenges and future perspective for the proper processing and utilization of advanced nanomaterials for the fabrication of devices. This book is intended for graduate students, researchers, and engineers working in the area of advanced nanomaterials, energy conversion, energy storage, sensors, and different types of optoelectronic devices.
