There are being increased efforts to obtain nanostructures between silicon (Si) and organic/polymer materials with solution processes prepared at low temperatures. Especially, there is a lot of work on zinc oxide (ZnO) in nanostructures. The reason for this interest is the high performance applications of ZnO semiconductors in many devices such as solar cells, gas sensors, biosensors, optoelectronic devices and piezoelectric systems [1]. In order to produce ZnO nanorods, there are different methods such as vapour-state (VS), RF sputtering, sol-gel, chemical vapour deposition (CVD), electrodeposition, thermal evaporation, metal organic chemical vapour deposition (MOCVD), and vapour deposition, spin coating [2]. Most of these methods have many disadvantages such as high temperature, long time, high cost equipment, complicated procedure. Among these methods, many studies have reported that aqueous chemical approaches such as '' hydrothermal synthesis '' are more convenient, practical and work well for producing well-ordered nanorods. During production, X-ray diffraction (XRD) analysis will be performed to determine whether the crystal structure of ZnO used as the seed layer is formed. Then, Scanning electron microscopy (SEM) measurements will be performed to determine if the ZnO structure grows in the "rod" form, and to observe the morphology and the grain size. Current-voltage (I-V) measurements at a wide temperature range will be performed to determine electrical and photovoltaic properties. In this study, hybrid solar cells will be produced consisting of p-type Si semiconducting substrate, ZnO nanorod and variable percentages of graphene/conductive polymer (Polyvinylpyrolidone (PVP)). It will be examined in detail for its performance and efficiency using SiO2/TiO2 double layer anti-reflective coating (ARC) for increased light absorption.
