The monograph should therefore play a binary role. First it should present the crystal structures of known chalcogenides. Second book should explain a wide range of preparation methods and basic chemical properties of sulphides, selenides and tellurides that can be important from practical point of view. These materials are referred to as compounds of technological future in optoelectronics and photovoltaics.
Recent years brought a rapid development in the research of new chemical compounds, especially in the field of photovoltaics. Most often these are materials not occurring under natural conditions and they can be formed only with the use of new methods of synthesis. Therefore, this innovative book should play a binary role. First, it should present the most important new photovoltaic materials. Second, this book presents their preparation methods, properties and characterization. It presents knowledge in the field of photovoltaics for both undergraduate and PhD students.
