Solar Energy’s Importance and Role in Advancing Society

The nation is facing energy crisis at faster rate. To meet this crisis, it is the prime need of the day to seek out an alternative source of energy. Conventional and non-conventional are the two sources for obtaining different types of energy. The conventional sources are fossil fuels such as gases, oils, coals, woods etc. and non-conventional sources are wind, bio-mass, ocean tides, geothermal and solar energy. More attempts are being applied to harness the solar energy by different technologies. This energy is available in vast amount and nonpolluting and harmless to the common creatures. The amount of solar energy received on the earth per sec is 1.353 KW/m2. This energy is converted into electrical energy by using dry and wet solar cells. The present paper deals with the characteristics of the solar cell which is the major candidate for converting solar energy.
