Type: article
Abstract: Squaraine (SQ) small molecules have been considered as efficient photoactive materials for organic photovoltaic (OPV) cells due to their simple synthetic routes, high absorption coefficients with tunable bandgaps and bandwidths in the visible-near infrared region, as well as high photochemical and thermal stabilities.The SQ donor and fullerene acceptor based OPV devices have realized the power conversion efficiencies of over 8%.In this paper, the progress of SQ donor and fullerene acceptor based OPV cells is reviewed, the effect of molecular structure, molecular aggregation and film morphology on the device performance is systematically summarized.The applied field of SQ donors in OPV cells is widened, and some proposals for future study are also given.Keywords organic photovoltaic cells; squaraine small molecules; donor materials; fullerene; progress 近年来, 能源紧缺和环境污染已成为制约经济社会 可持续发展的重要因素.为了解决日益严峻的能源和环 境问题, 人们把目光投向了新能源的开发和利用上.在 各种新能源技术中, 太阳能作为一种可持续利用的清洁 能源, 有着巨大的应用潜力, 越来越多的国家开始开发 太阳能资源, 寻求经济发展的新动力.在对太阳能的利 用中, 光伏发电技术是最有效的方式, 可将太阳能直接 转化成电能 [1] .目前光伏市场的主流是使用基于晶硅、 非晶硅薄膜、碲化镉多晶薄膜和铜铟镓硒薄膜等的无机 光伏电池.有机光伏(organic photovoltaic, OPV)电池是 近年来发展起来的一种通过有机半导体材料吸收太阳 光并使光子转换成自由电荷的技术, 被称为继第一代晶 硅光伏电池和第二代薄膜光伏电池之后的第三代光伏 电池.由于 OPV 的制备工艺简单、材料价廉易得
