【摘要】：有机-无机杂化的卤素钙钛矿材料在2009年首次应用在光伏器件中,而后有关此类型太阳能电池的报道数量呈井喷式增长.至2014年5月钙钛矿电池光电转化效率已接近20%,已超过有机及染料敏化太阳能电池的效率,且有望达到单晶硅太阳能的水平,成为光伏发电领域中的希望之星.在钙钛矿电池中,电子传输材料与吸收层的电子选择性接触对提高光电转化效率起到重要作用,尤其在正置结构器件中,电子传输层的介观结构直接影响钙钛矿的生长情况.同时,电子传输层的化学性质及其界面也会对电池的稳定性和寿命产生影响.本文总结了电子传输材料在该类电池中的研究现状和热点,并按材料的化学组分不同,将电子传输材料分为三类:金属氧化物、有机小分子和复合材料,详细地介绍了电子传输材料在钙钛矿太阳能电池中的作用和近来的最新进展.
[Abstract]:Organic-inorganic hybrid halogen perovskite materials were first used in photovoltaic devices in 2009. By May 2014, the photoconversion efficiency of perovskite cells was close to 20, which exceeded the efficiency of organic and dye sensitized solar cells. It is expected to reach the level of single crystal silicon solar energy and become a hopeful star in photovoltaic power generation. In perovskite batteries, the selective contact between electron transport material and absorption layer plays an important role in improving the efficiency of photovoltaic conversion. Especially in the positive structure devices, the mesoscopic structure of the electron transport layer directly affects the growth of perovskite. The chemical properties of the electron transport layer and its interface will also affect the stability and lifetime of the battery. This paper summarizes the research status and hot spots of the electron transport material in this kind of battery, and according to the chemical composition of the material, Electron transport materials are classified into three types: metal oxides, organic small molecules and composite materials. The role of electron transport materials in perovskite solar cells and recent developments are introduced in detail.
