ABSTRACT The first law of thermodynamics postulates that the total amount of energy in the universe is constant. The sun provides plant the food by photosynthesis. Thus the sun is a renewable energy sources of all the life on earth, The photovoltaic energy generated by sunsolar cell to absorb the sunlight which it transmitted as electric charge in the circuit .The solar panel transfers the energy from the sun by trapping the photon. and ejecting an electron from semiconductor to produce energy .semiconductor has an energy gap between valence electron and conductionTio2 is a wide band gap semiconductor.very wide and the energy from sunlight can not release electrons easily but if the exited electron are received from the blackberry juice then juice becomes slightly positive (oxidised),Thusin demand of an electron to become neutral. If electrode coated with graphite come in contact with blackberry juice and Tio2 and iodine electrolytewhich acts like a boat bringing electrons. This is the basic similar process which is observed and is known as photosynthesis in plants. The solar cell was fabricated on glass plate and tested for generation of voltage successfully in the sun.

Keywords: Blackbery, Glassplates, solar cell, I. INTRODUCTION Solar energy is the energy which comes from natural sources. These sources are available in abundancecan be naturally replenished. Therefore, for all practical purposes, these solar cell. Blackberry juice contains many water soluble chemicals that may cause a chemical reaction with one or both of the electrodes. So it may get some electricity from that.
