【摘要】：采用溶液旋涂法在銦錫氧化物(ITO)電極上制備氧化石墨烯(GO)薄膜作為有機太陽能電池(OPVs)的空穴傳輸層,通過調控旋涂轉速優(yōu)化了氧化石墨烯薄膜的厚度并研究了膜厚對于器件性能的影響規(guī)律。在此基礎上,通過紫外臭氧(UVO)處理和熱處理等方法進一步提升電池器件的性能。結果表明:在紫外臭氧處理和熱處理溫度為250℃時,所得電池器件的效率最優(yōu),達到3.16%,接近于使用經典聚(3,4-乙撐二氧噻吩):聚苯乙烯磺酸(PEDOT:PSS)材料的電池器件水平。這一結果表明具有低成本、可溶液加工以及優(yōu)異的光透過性等特點的氧化石墨烯會成為一種未來非常有前景的有機太陽能電池的空穴傳輸層材料。
[Abstract]:Graphene oxide (GOO) thin film was prepared on indium tin oxide (ITO) electrode by solution spin-coating method as the hole transport layer of organic solar cells (OPVs).The thickness of graphene oxide film was optimized by adjusting spin-coating speed and the influence of film thickness on device performance was studied.On this basis, the performance of the battery is further improved by UV ozone treatment and heat treatment.The results show that when the temperature of UV ozone treatment and heat treatment is 250 鈩，
