Low-temperature solution-processed tri-halide perovskite have been successfully used as light-absorbers and light-sources in many researches.The crystallinity and proper morphology are important factors for perovskites-based lasing devices.Here, we report a tow-step solvent-engineering process that comprising the N, N-dimethylmethanamide and dimethylsulfoxide as the binary solvent to fabricate a CH3NH3PbI3 perovskite thin filmbased on the PbI2 (solvent) complex layer.

界面缓冲层为钙钛矿型太阳能电池中极其重要的环节之一,针对电池的效率和稳定性,我们一方面合成了一种含有冠醚的富勒烯材料,研究表明该材料适合作为宽带隙、窄带隙及钙钛矿活性层的阴极缓冲层;另一方面,引入了PCBM\C60\LiF三叠层阴极缓冲层,电池效率和稳定性具有显著提高.另外,我们发展了一种溶剂退火的方法,完全避免了加热退火,结果表明,器件效率与热退火法制备的钙钛矿型太阳能电池相比大大提高.

染料敏化太阳能电池(DSSCs)是低成本、高性能太阳能电池的重要成员,目前制约它们进一步发展的一个因素在于高性能的对电极材料使用贵金属铂,其替代研究将能够进一步降低制作成本.铂的替代材料必须具备高导电性、高催化活性、高稳定性,同时还要具备资源丰富,加工成本低廉等特点,同时满足以上条件对于DSSCs对电极的探索是一个巨大的挑战.石墨化的碳纳米管材料具有高的导电性,但其催化活性不足.
通常情况下,电池器件需要在很高的温度下制备,因此用于电池制备的透明导电氧化物(TCO)必须是具有高温稳定性的材料.本论文[1]中,我们选择Ga掺杂ZnO(GZO)作为透明导电层制备染料敏化太阳能电池(DSSC),研究其热稳定性.在温度高达500℃的空气中热处理30min,GZO薄膜最低电阻率由5.5Ω/sq增加到8.3Ω/sq(仍低于10Ω/sq).其平均可见光透过率超过90％,最高可达96％,并

近二十多年来,以染料敏化太阳能电池为代表的有机太阳能电池以期高性能、低成本等优点引起了学术界和工业界的极大兴趣[1].研究探索新颖高效的敏化剂,特别是三芳胺类D-π-A型纯有机染料更是引起了广泛的关注[2].本文以吡咯并二噻吩为基础[3],设计与合成了三个有机染料(PSD-9,PSA-10,PST-11),研究了芳胺类电子给体对染料光伏性能的影响.基于该三个染料的光伏数据分别为,PSD-9: IP
吩噻嗪(PTZ)与吩噁嗪(POZ)同属氮杂蒽类化合物，本文合成了两个分别基于吩噻嗪与吩噁嗪的D-π-A型染料分子，并将其应用于染料敏化太阳能电池中，对比分析其光电性能差异(如下图所示)。结果表明，基于"O"原子的吩噁嗪类染料性能明显强于基于"S"原子的吩噻嗪类染料。
