碳材料在染料敏化太阳能电池和钙钛矿太阳能电池对电极中的应用进展

染料敏化太阳能电池和钙钛矿太阳能电池是目前太阳能电池领域的研究热点,但这两种电池中使用的传统对电极材料,如Pt和Au等稀有且价格昂贵,不利于大规模量产。碳材料作为除Pt,Au等之外的另一种候选材料,其种类丰富且成本低廉,作为对电极应用在这两类电池中具有逐渐接近甚至超越传统电池的光电转换效率,表现出良好的应用前景。本文综述了作为两类电池对电极的碳材料具备的结构、性能及对电池光伏性能的影响,着重介绍各种形式的碳材料应用于对电极的最新研究进展,并指出现有研究存在的局限性与待解决的问题,讨论了碳材料对电极未来的研究方向。

Novel Progress on Application of Carbon Materials as Counter Electrode in Dye-sensitized Solar Cells and Perovskite Solar Cells

Dye-sensitized solar cells(DSSCs)and perovskite solar cells(PSCs)are the research focuses at present in the field of solar cells.However,the commonly used counter electrodes(CEs)in these two solar cells,such as Pt and Au,are rare and expensive,they are not suitable for mass production. Low-cost and abundant carbon-based materials can substitute Pt and Au in DSSCs and PSCs as CEs, showing gradually approaching or even higher photoelectric conversion efficiency and suggesting a bright future.The structure and electrochemical properties of carbon-based materials as well as the photovoltaic performances as CEs were reviewed in this paper.The recent advances achieved by car-bon-based CEs were highlighted,and the limitations and unsettled problems in present researches were also pointed out,and finally,the possible directions for further research were discussed.
