THE RELATIONSHIP BETWEEN ATOMIC NUMBER & EFFICIENCY AT DYE SOLAR CELLS
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 8
Abstract
In this work the effect of changing the anode of polymer solar cell on their performance was experimentally investigated .The cells were fabricated from ITO which act as a cathode beside MEH PPV ,Ecrchrom Black T and Rohadamin B dyer . The anodes which c are AL, GL ,AU with atomic number 13 , 47 and 79 were used . It was found that the efficiency of the solar cell of AL, GL ,AU electrode for Ecrchrom dye are 1.66, 1.59 , and 1.58 Respectively the efficiency for Rohadamin , Ecrchrom Black T dye are 1.49, 1.48 and 1.46 respectively these results shows clearly that the efficiency increases as the atomic number decreases this conforms with the fact that energy gap increase with the atomic number.
