摘要
以甲烷作为反应气体,利用化学气相沉积法在硅衬底表面上沉积石墨烯薄膜,制备了石墨烯/硅肖特基太阳能电池.利用原子力显微镜和拉曼光谱观察了石墨烯薄膜的表面形貌,并用紫外-可见光光谱仪和光-电流测试仪器研究了石墨烯样品和太阳电池的光电特性.实验结果表明:制备的石墨烯薄膜厚度为几个原子层,薄膜表面均匀,并具有良好的电学特性,石墨烯/硅太阳能电池的能量转换效率可达3.7%.
Graphene/Si Schottky solar cell was fabricated by depositing graphene thin film on Si substrate by chemical vapor deposition with CH4 as reactive gas. The surface morphology of the graphene film was observed by atomic force microscope and Raman spectroscopy. The optoelectronic characteristics of the graphene/Si Schottky solar cells were measured. The results indicated that the deposited graphene thin film was very large and uniform with a thickness of few atomic layers, and the film had good electrical properties. The conversion efficiency of the solar device was up to 3.7%.
