摘要: In the present study, we propose low porosity and short length of TiO2 nanotubes (NTs) as underlayer in dye-sensitized solar cells (DSSCs). Photovoltaic characteristics DSSCs with without NT are compared using various electrochemical analyses. Low by small pore diameter, thick walled geometry help efficient charge transfer reduced recombination at interface nanoparticles (NPs)/Ti substrate. As a result, can achieve conversion efficiency 6.89% for underlayer, which is about 20% higher than that obtained from only NPs layer.
