          Thin Film Solar Cell Techology     - By Sudipta Kundu, PG Student                                                                  Department of Renewable Energy Introduction : Thin-film solar cells were originally introduced in the 1970s by researchers at the Institute of Energy Conversion at the University of Delaware in the United States. Thin-film solar cells (TFSCs) are the second-generation solar cells that have multiple thin-film layers of photovoltaic or PV materials. These solar cells have a very thin layer of thickness (few nanometers) compared to conventional P-N junction solar cells. These layers ar...

    ORGANIC PHOTOVOLTAIC CELLS Name – Poushali Gope, PG Student, Department of Renewable Energy Organic photovoltaic cell research has developed during the past 30 years, but especially in the last decade it has attracted scientific and economic interest triggered by a rapid increase in power conversion efficiencies. This was achieved by the introduction of new materials, improved materials engineering, and more sophisticated device structures. Today, solar power conversion efficiencies in excess of 3 % have been accomplished with several device concepts. Though efficiencies of these thin-film organic devices have not yet reached those of their inorganic counterparts the perspective of cheap production (employing, e.g., roll-to-roll processes) drives the development of organic photovoltaic devices further in a dynamic way. Though common materials used for photovoltaics (i.e., the conversio...
