Verification of necessity of one-dimensional titania nanoscale materials for dye-sensitized solar cells

► Three one-dimensional titania nanoscale materials synthesized in our laboratory show high conversion efficiency around 9%. ► Necessity of highly crystallized 1-dimensional titania nanoscale materials was elucidated by theoretical consideration. ► The consideration was verified by systematic experiments based on the measurements of (I-V) relation and EIS analysis.
