|標題:||Improvement of Photovoltaic Performance of Dye-Sensitized Solar Cell by Post Heat Treatment of Polymer-Capped Nano-Platinum Counterelectrode|
|摘要:||A post heat treatment is developed to improve the “two-step dip coating process” in which poly-N-vinyl-2-pyrrolidone (PVP)-capped Pt nanoclusters are deposited with the aid of appropriate conditioner on transparent conductive oxide (TCO) glass as counterelectrode for dye-sensitized solar cell (DSSC). Charge transfer resistance (RCT) is found only 0.56 -cm2 for this annealed counterelectrode. The improvement of RCT is attributed to the removal of conditioner by the post heat treatment at 270 oC, which enhances the electrical contact between the Pt nanoclusters and the TCO glass, and thereby accelerates the charge transfer. The DSSC employing this annealed counterelectrode achieves a high energy conversion efficiency over 8%.|
