中文摘要：

当光射入染料敏化太阳能电池（DSCs）时，有部分光不能被染料、电解液、导电玻璃等吸收，这部分光将透过电池而未被利用，本研究利用普通镀铝玻璃镜做为背底，将这部分透射光通过背反射重新射入电池来提高DSCs的光电转换效率。研究结果表明，背反射能大幅度提高DSCs的短路电流，短路电流的增加率随着测试遮光罩开孔尺寸的增加而增加，并且随纳米TiO2薄膜厚度的增加而降低。

英文摘要：

When light illuminating on the dye-sensitized solar cells （DSCs）, some of light transmits the cell due to the cell materials, such as dye, electrolyte and ITO-glass, can not absorb all light. In this work, the transmitted light was re-illuminated into DSCs through back reflection of a common surface aluminized mirror in order to enhance photoelectric conversion efficiency of DSCs. The result shows that the short circuit of DSCs can be enhanced greatly by back reflection, the increase rate of short circuit increases as the size of window of measurement mask increases and reduce as the thickness of nato-TiO-2 film increases.
