在這能源短缺的時代，開發替代能源已經成為主要課題。利用光觸媒特性所製成的色素增感型太陽能電池，因二氧化鈦光觸媒受到紫外光照射才產生電子躍遷，吸收光的頻率區域狹小，實用性不高。因此研究氧化鋅、二氧化錫與二氧化鈦混合，是否能提升該電池的轉換效率。藉由各種變因的探討，從中選取最有利的方式，使太陽能電池發揮更大的效益。除了以溫度、電解質、混合比例等因素外，增加電極面積以及串聯均可提高電壓與電流，以增加日常生活的實用性。如不斷的改進發展，諸如電解水、使小燈泡發光，甚至各種小家電用品的使用，都可應用於其中。In times of energy shortage, exploring the alternative energy has already become a main issue. The dye solar photocell is using photocatalyst characteristic. Because the electron transition is caused by lighting up the titanium dioxide photocatalyst by the ultraviolet, the frequency of spectrum is narrow and small. It is thus impractical. Therefore, we research whether or not the mixtures of zinc oxidize and tin oxide with titanium dioxide can improve the conversion efficiency of the dye solar photocell. Through discussion on various kinds of factors, we can choose the best way to make the dye solar cell yield more efficiency. In addition to the factors such as temperature, electrolyte, mixed proportion, etc., increasing the area of electrodes and contact can improve the voltage and electric current. That way we can increase the practicability for daily use. With constant improvement, it can be applied to many kinds of things, such as electrolyzing water, small bulb lights, even small household appliances.
