▎ 摘　　要

In this paper we obtained hybrid ZnO/3D graphene structures through hydrothermal growth of ZnO nanoparticles on 3D graphene substrate obtained by chemical vapour deposition (CVD) method in order to use them as electrode in solar cells. The influence of hydrothermal process parameters on structural and morphological properties of the obtained ZnO nanoparticles was studied. The temperature and the duration of the process had an important influence on the ZnO nanostructures obtaining.
