Abstract：The current-voltage and electroluminescence characteristics of dye-sensitized solar cells (DSSCs) are investigated under forward dc bias in a dark environment at room temperature. The results show that the presence of dyes can play an important role in improving device performance, and also produce defects at the TiO2/dye/electrolyte interfaces, which dominate the electron-hole recombination process and become a limiting factor in obtaining high-efficiency DSSCs. The goodness of fit between measured and calculated data supports these conclusions.
