In the present scenario, nanomaterials have played an essential role in making human life more functional, accurate and fast while creating a space for development of new nanotechnology-based miniaturized devices. Devices like smart mobile phones, smart watches, mini laptops, mini data storage devices etc. are being used in our day to day life. All these smart devices require energy supply in such a way that the amount of energy required for the device will be more enough without disturbing the size of the devices. For this aspect, the role of nanomaterials is very important in the field of energy conversion and energy storage to enhance the energy storage/supply for smart devices. Graphene, a 2-D sp2 hybridized nanomaterial, has found great attention in the field of device application. It has excellent characteristics, like high carrier mobility, specific surface area, thermal conductivity, optical transmittance and flexibility with mechanical properties. This chapter provides an overview and sheds light on the application of graphene in different devices for distinct sectors of energy employment such as opto-electronic and energy storage. The energy application is divided into two parts, namely energy conversion and energy storage. So, in the first part of the chapter basic principles and detailed background of graphene for energy conversion such as solar cells is provided. While, the second part focuses on the applications of graphene in energy storage applications such as capacitors and batteries. The fusions of these two devices with nanotechnology have resulted in advancement of a research in area of nano sciences. Additionally, the recent research and new insights for further progress and practical utilization of graphene in the above sectors are also addressed.
