摘　　要：近几年,有机-无机杂化钙钛矿太阳电池迅速兴起并且获得了媲美硅基电池的效率,受到了学术界以及产业界的高度关注。随着效率的提高,如何解决稳定性、大面积制备等问题也迅速被提上日程。汽相薄膜制备方法是目前广泛应用于制备大面积致密半导体薄膜及器件的一种工业技术。自2013年Snaith团队成功实现钙钛矿薄膜的真空汽相沉积以来,汽相制备技术在钙钛矿薄膜及器件制备领域也获得越来越多的研究。本论文将对气相法制备钙钛矿薄膜和器件的研究进行综述。重点介绍气相法制备方法的发展及汽相制备方法中一些共有的物理问题,包括MAI分子蒸发的弥散性问题;真空度对分子扩散及薄膜形态的影响以及温度对固态反应的影响。最后将简单讨论进一步提高材料和器件特性可以采取的方案。In recent years,organic inorganic hybrid perovskite photovoltaic device has developed rapidly.The photoconversion efficiency is now comparable to the efficiency of silicon photovoltaic device.How to solve the problem of stability and large scale fabrication are quickly put on the agenda.Thin film deposition by vapor evaporation method is widely used in the preparation of desne,large scale semiconductor thin films and devices in industrial application.Since the first demonstateion of vacuum deposition of perovskite thin film in 2013 by Snaith et al,vapor deposition technology has attract more and more attention.In this paper,the vapor synthesis of perovskite thin films and its photovoltaic performance are reviewed.The paper focuses first on the development of preparation methods,and then on the common physical problems,including the problem of evaportion of MAI molecule,vacuum condition on the molecular diffusion and thin film morphology,and influence of temperature on the solid state reaction.Finally,the ways to further improve the systhesis of thin film and photovoltaic performance will be discuss.
