隨著科技日新月異，能源的收集方式逐漸多樣化。在太陽能這一部分也毫不例外，而太陽能電池的結構更是五花八門。
本篇論文旨在利用二維材料石墨烯與氧化鋅和矽基板結合，並利用串聯和金屬奈米粒子的加成方式來提高太陽電池的開路電壓，進而將整體結構運用於水的電解上。
為了達成電解水產氫燃料的目標，我們利用了串聯的方式提升了元件結構整體的開路電壓，試著將原本開路電壓只有0.3V左右的單一元件增加到滿足電解水反應產生所需之電壓閥值(約1.23V)。同時利用尖端放電的原理，在元件表面覆上Pt奈米粒子，來增加元件表面的粗糙度來達到電場增強的效果，以力求串聯結構可在開路電壓小於1.23V的情況下，使電解水反應產生。

As the rapid development of technology, the ways of conserving enegy are diversified. Particularly, when it comes to solar cells, there are various kinds of structures.
In this thesis, we demonstrated two types of solar cells mainly made of graphene and other materials such as silicon and zinc oxide.
Furthermore, in order to apply the cells into water splitting, we added some platinum nanoparticles on the cells and connected devices in series to improve their open-circuit voltage.
