- Abstract:
- Since the fossil fuels are exhausting, energy issue becomes the primary problem for the whole world. Solar energy is supposed to prevail in the future world energy structure. Graphene, which has the fastest carrier mobility among known materials, is of brilliant chemical stability and highly transparency in the visible light range. Therefore, Graphene is suitable material for photovoltaic applications. Graphene-Silicon（Gr-Si） solar cell, which is a new kind Si-based Schottky junction solar cell, has a great application potential due to its simple and low-cost fabrication method. Since it was first reported in year of 2010, the Gr-Si solar cell has attracted considerable interests. Rapid developments of power converse efficiency from 1.65% to 15.6% have been witnessed. In this article, the device structure and working mechanism of Gr-Si solar cells are introduced. Meanwhile, recent development and breakthroughs concerning optimization in reflection of Si surface, work function and conductance of Gr films, quality of Gr-Si interface and n-Gr/p-Si solar cells have been reviewed.
