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.

Development of a high-efficiency laminated dye-sensitized solar cell with a condenser lens.

Dye-sensitized solar cells have slightly lower photoelectric efficiency than silicon solar cells. Researchers have investigated various ways to address this problem. In this paper, we found that the optimized separation between the condenser lens and the cells was 8 mm. The cell efficiency increased from 2.5% to 8.3% compared to two isolated cells without a lens. If the efficiency of the basic cell can be increased sufficiently, it should be possible to commercialize the product.
