Characterization of the Dye-Sensitized Solar Cell

Dye-sensitized solar cells which combine the unique properties of both the organic compound and inorganic compound have attracted the attention of scientists. This project was designed to characterize several factors which could be potentially changing the efficiency of the cells. An increase of output potential when the cell was heated over a short period of time and when thicker TiO2 was applied were observed followed by the decreasing in efficiency of over-coating and over-heating. The dark current after a long illumination was also confirmed in this project. The evidence strongly supports the electron trapping mechanism for generating the dark current
