Photovoltaic Generations

All technologies of PVs are different -depend upon the materials and structures which consequently effect the efficiency of the energy conversion. Photovoltaic (PV), or solar cells can be made of many semiconductor materials.Each material has unique strengths and characteristics that influence its suitability for specific applications.For example,PV cell materials may differ based on their “crystallinity”,band gap, absorption, and manufacturing complexity.Solar cells are usually divided into three main categories also called ‘generations’.
