Abstract

Solar cells offer an opportunity to diversify energy sources. However, it is necessary to improve its conversion efficiency and reduce the production cost for the development of a sustainable technology. Nanomaterials may contribute to the development necessary to achieve more efficient use of solar energy. The incorporation of nanocomposites is a strategy to improve the separation and charge transport in solar cells to improve energy conversion. In this paper we reported the synthesis and characterization of nanocomposites involving carbon nanotubes and quantum dots of CdTe, dispersed in water, and carbon nanotubes coated with a nanolayer of silica. These nanocomposites have properties that allow applications in photovoltaic devices.
