Abstract: In this research, hybrid solar cells created on the basis of (TiO2/ZnO), where the performances of two kinds of the semiconductor are similar to make paste that is applied as electrode dye molecules absorb photons of falling light rays. These solar cells have preferred an alternative to traditional photovoltaic cells that rely on dyes due to improved properties performance. The dyes solar cell usually consists of four parts conductive glass (FTO), an electrolyt solution, dyes and TiO2/ZnO electrode. solar cell depends on some characteristics, including technique and preparation of paste (TiO2/ZnO), which is important to obtain the best efficiency and used the method of Doctor blade. We proved that mixed dyes give higher conversion efficiency than if they were alone such as ruthenium dye (Ru) has better photovoltaic properties compared to other two dyes eosin (EO) and methyl red (Mth). Photovoltaic parameters like, Overall conversion efficiency () of glass substrate solar cell film thickness (16 m) with efficiency three dyes of ruthenium, eosin and meth red were found (2.11 %, 0.84 %and 0.43 %) respectively, while best efficiency (2.29 %) was found when mixing the together dyes with each other 3ruthenuim dye +7methyl red dye at percentage 75 % / 25 % under 40 mW/cm2 illumination.
