Study of the Influence of Nb2O5 in ZnO Solar Cells.

The solar cells of semiconductors oxides have been largely studied. The zinc oxide (ZnO) and niobium oxide (Nb₂O₅) used in this work presented important physical-chemical characteristics in use of photovoltaic devices. The Nb₂O₅ presents the capacity of minimizing effects of charge recombination in the process of energetic conversion of solar cells. The oxides used in this work were characterized by the technique X-ray diffraction. The solar cells containing 5% of Nb₂O₅ presented of best results in a relationship of the electron transfer process, reaching the efficiency of 0.42%. [ABSTRACT FROM AUTHOR]
