The important of sustainable energy supply in today’s world has led to widely efforts by researchers to find an alternative source. In this paper we present a renewable resource called solar cell. Also, traditional solar cells is analysed which help us design new devices with high conversion energy. In other world to solve the problem and limitations of old solar cells devices like low efficiency, expensive operating process and not economically to use in large scale, perovskite solar cells (PVCs) proposed. Perovskite solar cells have the highest capability compared to other solar cells like Si-based photovoltaic solar cells and CFTs solar cells, with high efficiency and cost effectiveness. It is noteworthy that the discovery of new materials with unique properties such as graphene help researchers to improve solar cells efficiency. Beside this graphene-based perovskite devices are enabled rapid progress with high efficiency. Using graphene on the top of the perovskite layer in PVCs not only optimize PVCs performance to convert more light to sustainable energy but also improvement stability and PCE.. To note developed solar cells technology pave the way for easy processing, mass production and commercialization.
