To increase the efficiency of the Dye sensitized solar cell, 0.25 g of tetropropylammonium iodide salt (TPAI) was added to a polymer electrolyte based on polyethylene oxide (PEO). At the same time, ionic conductivity increased to 18,117 . The increase in conductivity was associated with an increase in the density of the number of charge carriers. The highest conversion efficiency of incident photons is 45.5%.
