Abstract:
The study of the materials suitable for use in photovoltaic structures, as well as the design of such structures, represents a priority of the research in the field of solar energy. Whatever will be the photovoltaic structures, systematic researches must be done on each layer of these devices, on the interactions between successive layers and on the improving of transparent conducting oxide (TCO) contacts. Such contacts have to be made of low-cost materials, and to have high conductivities and high transparencies in the whole visible spectrum. We report here on structural, electrical and optical characterizations of nanostructured ZnO thin films used as photosensitized electrodes in the Hybrid Organic/Inorganic photovoltaic cells applications. Also a thorough investigation of Hybrid Organic /Inorganic photovoltaic cells based on ZnO films and organic dye thin films was performed.
Structural, morphological, electrical and optical properties of each component layer are investigated. Typical parameters of the prepared photovoltaic structures are determined and their performances related with the properties of the component films are discussed.
