In dye-sensitized solar cells (DSSCs), the back transfer of photo-generated electrons from FTO glass to triiodide ions in an electrolyte is important loss mechanism, which leads low cell efficiency. Recently, this electron was greatly suppressed by introduction a compact blocking layer, prepared treatment solution. present work, more detailed treated surface conditions on substrate were investigated and DSSC performances correlated with morphology as well dark current behavior.
