Evaluation of characteristics for dye-sensitized solar cell with reflector applied.

Dye-sensitized solar cells have slightly lower photoelectric efficiency than silicon solar cells. Researchers have investigated various ways to address this problem. This study improved the efficiency of a dye-sensitized solar cell by re-driving it with a reflector, reusing discarded light after it was absorbed. The reflector increased efficiency by about 50%, by increasing the size of the pattern shape and increasing the distance of the reflector.
