Over recent years, the need to find solutions to the environmental problems currently faced by our planet has become a major issue. Given that fossil fuel resources are becoming rapidly depleted and in view of the considerable environmental damage they cause, the time has come to develop alternative methods of energy production.
The sun is an abundant source of clean energy. The development of the aerospace industry in the middle of the 20th century saw an increase in the number of studies on photovoltaic (PV) conversion. In the meantime, progress towards making this type of energy accessible to the general public has been made on a number of fronts.
Having said this, a considerable amount of research work is still being undertaken. The development and improvement of these technologies involve characterizing the various stages of the process (in chemical, electrical, mechanical and optical terms). UV/Vis/NIR spectroscopy is used to study optical properties
