Biography

Jan Valenta is professor of quantum optics and optoelectronics at the Department of Chemical Physics and Optics, Charles University, Prague. His research is oriented toward optical properties of semiconductor nanostructures, especially silicon. He is developing special spectroscopy set-ups and methods to measure photo- and electroluminescence spectra (down to single nano-objects), optical gain, and absolute quantum yields. His other interests include the history of science, scientific photography, and science-for-art applications. He is co-author (with I. Pelant) of the textbook Luminescence Spectroscopy of Semiconductors (Oxford, 2012).

Salvo Mirabella received his laurea (1999) and PhD (2003) in physics from the University of Catania, Italy, and is now researcher at the Institute for Microelectronics and Microsystems, National Council of Research (CNR IMM), Italy. His research activity is mainly experimental, focusing on group IV advanced materials for applications in photovoltaics (light absorption mechanisms in Si- or Ge-based nanostructures, sunlight-energy conversion, and transparent conductive electrodes) and microelectronics (point-defect engineering and dopant diffusion in crystalline or amorphous semiconductors and ion beam modification of materials).

"It is commonly accepted that nanostructures, whose properties can be conveniently tuned by size adjustments, will provide the materials basis for the next generation of highly efficient solar energy solution. That is in particular true for photovoltaics, possibly the most elegant solar energy harvesting strategy. There are many reasons why the first-generation PV is dominated by silicon; most of them will apply also to the next-generation solutions and that defined importance of nano-Si for the future photovoltaics. This book provides an excellent introduction to the field and a comprehensive overview of the state of the art in this vividly developing discipline, with experimental as well as theoretical advancements being presented in parallel."
