In this research ZnO hexagonal nanorods solved in hydrothermal with 0.05M and 0.025M concentrations(MEA) has been grown at 2.5 and 5hours on the FTO. For construction of solid phase of solar cell, combination of CH3NH3PbI3, Spiro-OMeTAD and gold has been used. For investigation of structural and optical specification of nano rods by SEM, XRD, DRS and determining photo electro chemical parameters of cell by voltage-current analysis has been done. Results has been shown that efficiency is reached from 5.42% to 6.41% because of increasing the synthesis time by two times which is caused to increase the average length of nanorods from 300 nm to 650nm. By 50 percent decreasing of concentration of MEA, the average diameter of the nanorods has been decreased from 95 nm to 50 nm and finally efficiency of the cell has been 1.5% decreased. Results has also been shown that the efficiency of synthesis nanorods with fully concentration of MEA during 5 hours is 6.41% and the efficiency of produced nanorods with half of concentration of MEA during 2.5 hours is 4.98%.
