摘要: 首先制备出量子点(QDs)/TiO2涂料,分别采用丝网印刷法与刀刮法将涂料涂覆于ITO/PET柔性基底上,结果表明刀刮法制备量子点敏化太阳电池(QDSCs)效果更佳,且具有普适性。基于铜片对电极所组装的ZnCuInSe,CdSe和CdSeTe量子点半柔性QDSCs最高效率分别达2.83%,2.46%和1.99%。另外,我们对石墨纸进行表面化学修饰以提高亲水性,再通过简单的连续离子交换吸附法(SILAR)在石墨纸上负载CuxS纳米粒子,制备出CuxS/GP柔性对电极,进一步组装成全柔性QDSCs,获得了2.13%光电转化效率。

Abstract: The pastes containing quantum dot (QDs)/TiO2 were first synthesized, and then screen printing and doctor blading were employed for coating the pastes onto ITO/PET flexible substrates. The results show that doctor blading was universal and more effective to obtain high efficiency quantum dot sensitized solar cell (QDSCs). The assembled ZnCuInSe, CdSe and CdSeTe semi-flexible QDSCs obtained high conversion efficiencies of 2.83%, 2.46% and 1.99% respectively when brass-based counter electrodes (CEs) were used. Furthermore, surface chemical modification was first carried out on graphite paper (GP) to improve the hydrophilicity, then CuxS nanoparticles were grown on GP via successive ionic layer adsorption and reaction (SILAR). The as-prepared flexible CuxS/GP CEs exhibited satisfactory performance and the assembled fully flexible ZnCuInSe QDSCs obtained high efficiency of 2.13%.
