摘要:

 隨著化石能源的日益枯竭，能源問題成為當今世界需要解決的首要問題。在將來的世界能源結(jié)構(gòu)中，太陽能有望占據(jù)主導地位。石墨烯是已知材料中載流子移動速度最快的，它化學穩(wěn)定性好，且在可見光波段具有極高的透光性，非常適合應用于光伏領(lǐng)域。石墨烯-硅太陽電池是一種新型的硅基肖特基結(jié)太陽電池，具有制備工藝簡單，制作成本低等優(yōu)點，應用潛力巨大。自2010年首次報道以來，器件的光電轉(zhuǎn)換效率已由1.65%迅速提升至15.6%，得到了廣泛的關(guān)注。簡要介紹了石墨烯-硅太陽電池的基本結(jié)構(gòu)和工作原理，從硅表面反射率優(yōu)化、石墨烯導電性和功函數(shù)優(yōu)化、石墨烯-硅界面優(yōu)化和n型石墨烯-硅太陽電池等4個方面概述了石墨烯-硅太陽電池的發(fā)展歷程、研究現(xiàn)狀和未來趨勢。

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 high transparency in the visible light range. Therefore, Graphene is suitable material for photovoltaic applications. Graphene�睸ilicon（Gr�睸i） solar cell, which is a new kind of Si�瞓ased Schottky junction solar cell, has a great application potential due to its simple and low�瞔ost fabrication process. Since it was first reported in year of 2010, the Gr�睸i solar cell has attracted considerable interest. 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�睸i 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�睸i interface and n�睪r/p�睸i solar cells are reviewed.
