Abstract: In this research, hybrid solar cells created on the basis of (TiO2/ZnO), where the performances of two kinds of thesemiconductor are similar to make paste that is applied as electrode dye molecules absorb photons of falling light rays.These solar cellshave preferred an alternative to traditional photovoltaic cells that rely on dyes due to improved properties performance. The dyes solarcell usually consists of four parts: conductive glass (FTO) , an electrolyt solution, dyes and TiO2/ZnO electrode. solar cell depends onsome characteristics, including technique and preparation of paste (TiO2/ZnO) , which is important to obtain the best efficiency andused the method of Doctor blade. We proved that mixed dyes give higher conversion efficiency than if they were alone such asruthenium dye (Ru) has better photovoltaic properties compared to other two dyes eosin (EO) and methyl red (Mth). Photovoltaicparameters like, Overall conversion efficiency (η) of glass substrate solar cell film thickness (16 µm) with efficiency three dyes ofruthenium, eosin and meth red were found (2.11 % , 0.84 %and 0.43 %) respectively, while best efficiency (2.29%) was found when2 mixing the together dyes with each other 3ruthenuim dye +7methyl red dye at percentage 75 % / 25% under 40 mW/cm illumination .
