Photovoltaic performance of dye-sensitized solar cells based nanoporous-network Nb2O5

Abstract

In this research, sputtered niobium metal on FTO glass was used as an initial material. Fabrication of nanoporous network Nb2O5 has been conducted via anodization technique and tested as a photoanode in dye-sensitized solar cells (DSSC). The nanoporous network Nb2O5 with N3 dye has successfully demonstrated 1.3 to 3.5% efficiency based on ∼3.5 and 5.0 µm thicknesses. The high performance of the nanoporous network Nb2O5 is expected due to long electron life time as observed from the voltage decay measurement.
