The book represents a thorough study of Tin oxide doped Fluorine SnO2: F as an alternative to the well known member of transparent conductive oxide TCO family, Indium Tin Oxide (ITO) as it has some restrictions. The TCO family has a unique property of high transmission to visible light, high reflection to infrared with wavelength greater than 2 mico m. and conductive to electricity like a metal. Based on that, it has wide application in optoelectronic solar energy generation and saving devices.
