Abstract: A light-trapping cancer cell stage testing method includes: measuring a first average escape velocity or range of first cancer cells and a second average escape velocity or range of second cancer cells whose stage is known and differ from that of the first cancer cells and whose types are known; utilizing the first average escape velocity and the second average escape velocity to calculate a reference ratio to build a database; selecting stage-unknown cancer cells and measuring an escape velocity of the stage-unknown cancer cells (type-known); utilizing the escape velocity of the stage-unknown cancer cells and an escape velocity of reference-stage cancer cells to calculate a ratio; and determining a stage of the stage-unknown cancer cells with a result comparing the ratio of the escape velocities for the stage-unknown cancer cells with the reference ratios stored in the database.

Abstract: A dye-sensitized solar cell includes a first substrate, a first electrode, a semiconductor layer, a thin photosensitive dye layer, an electrolyte layer, a second electrode and a second substrate. The first electrode is formed on the first substrate as a working electrode, the semiconductor layer is formed on the first electrode and the thin photosensitive dye layer is formed on the semiconductor layer by ultrasound-treating the semiconductor layer which is immersed in a photosensitive dye solution. The second electrode is formed on the second substrate as a counter electrode and the electrolyte layer is disposed between the semiconductor layer and the second electrode.
