ABSTRACT Photovoltaic (PV) is a method of generating electrical power by converting sunlight directly into direct current using semiconductors that exhibit the photovoltaic effect .The photovoltaic power generation employs solar panels composed of a number of solar cells containing a photovoltaic materials. The paper aims to collect the literature pertaining to solar photovoltaic cell, photovoltaic conversion efficiency and analysis of the literature of photovoltaic power generating plant. India lies in t h e sunny regions of the world. Most parts of India receive 4-7 kWh (kilowatt-hour) of solar radiation per square metre per day with 250-300 sunny days in a year. Since the invention of solar photovoltaic in the year 1839, the research has grown up. Now a day the emphasis is on the efficiency increase in SPV system and simultaneously to reduce the cost and to increase its life. The increasing costs of electricity, reducing fossil fuels, emphasis on solar energy usage etc. are a number of factors favoring the SPV research. There is a difference between the demand and supply of electricity. To fill the gap solar photovoltaic generation is one of the best solutions. The literature review is studied in this paper for research in the area. Keywords SPV; photovoltaic cell, Electrical efficiency, Power generation I. INTRODUCTION The solar photovoltaic electricity generation is the promising technologies by converting the incident solar radiation into electricity. Solar electricity generation is still not able to compare with energy conversion technology with the fossil fuels even it is comparable if subsidies. The
