Fortunately, we have renewable energy sources which neither run out nor have any significant harmful effects on our environment. Harvesting energy directly from the sunlight using photovoltaic (PV) technology is being widely recognized as an essential component of future global energy production. In this thesis, intensity dependence and a brief over view regarding photovoltaic properties of polymer based bulk heterojunction solar cell is presented and discussedenThe Photovoltaic ParametersThesis
